From Quantum Mechanics to Quantum Internet [1, 2, 3]
As traditional computing approaches the physical and economic limits of Moore's Law, the industry faces increasingly difficult challenges in advancing performance. Moore's Law, which has driven the exponential growth of computing power by shrinking transistor sizes, is now encountering significant barriers. With transistors approaching atomic scales, further miniaturization becomes impractical due to several key factors. One major issue is the emergence of quantum effects at these tiny scales, where electrons can "tunnel" through barriers (a phenomenon known as leakage current), leading to unpredictable behavior and power inefficiencies. Additionally, as transistors shrink, they generate more heat, and classical cooling systems struggle to dissipate this heat effectively without damaging the delicate components. These limitations cause classical computing technologies to face diminishing returns in terms of performance, power efficiency, and cost, making it increasingly expensive and difficult to maintain the rapid technological advancements that society has come to expect.
Quantum computing surpasses classical computing by overcoming the limitations imposed by Moore's Law, offering a transformative approach to handling complex tasks. While classical computers process information linearly, quantum computers use superposition, allowing them to perform parallel computations and solve problems much faster. This advantage is particularly evident in fields like cryptography and quantum simulations, where classical systems struggle. Quantum computers also promise breakthroughs in simulating molecular behavior and materials, which classical systems find computationally overwhelming. Additionally, their potential for energy efficiency and scalability makes them poised to revolutionize industries as they advance in reliability and size.
The history of quantum information theory is deeply intertwined with the development of quantum mechanics and computer science, which initially developed as distinct fields but gradually converged as quantum phenomena became relevant to computation. In the early 20th century, classical physics faced challenges like the ultraviolet catastrophe and unstable electron orbits, leading to the birth of quantum mechanics. Erwin Schr?dinger and Werner Heisenberg formulated quantum mechanics in the 1920s, explaining the wave-particle duality at atomic scales and providing a new framework for understanding microscopic systems. These developments laid the groundwork not only for quantum information theory but also for quantum computing and, later, the quantum internet.
During World War II, both quantum mechanics and classical computing found practical applications—quantum physics played a crucial role in nuclear physics for the Manhattan Project, while early digital computers were used for cryptography. In the post-war decades, quantum mechanics and computer science began to intersect more directly, particularly when Paul Benioff introduced the quantum Turing machine in 1980, applying quantum mechanics to computational theory. Around the same time, Yuri Manin and Richard Feynman proposed that quantum-based hardware could simulate quantum systems more efficiently than classical computers, laying the foundation for quantum computing. Feynman’s insights highlighted the potential of quantum computers to handle problems too complex for classical computers, such as simulating quantum dynamics.
By 1984, Charles Bennett and Gilles Brassard had applied quantum mechanics to cryptography, developing quantum key distribution (QKD) to enhance information security. This marked the first major application of quantum theory to information security, and it also set the stage for future advancements in the quantum internet, where quantum communication techniques promise to provide ultra-secure transmission of information. This development was a key milestone in quantum information theory.
Throughout the mid-1980s and early 1990s, quantum algorithms began to emerge, including Deutsch’s algorithm (1985), the Bernstein-Vazirani algorithm (1993), and Simon’s algorithm (1994). These algorithms demonstrated the power of quantum parallelism, which allows quantum computers to process multiple possibilities simultaneously due to quantum superposition. David Deutsch’s contribution with his algorithm was crucial because it was the first to show how quantum computers could solve certain problems faster than classical computers, providing a foundation for quantum computation. His work on the quantum Turing machine and the Church-Turing-Deutsch principle also established the framework for thinking about quantum systems as general-purpose computing devices. This computational advantage, known as quantum parallelism, set the stage for what would later be termed quantum supremacy—the point at which quantum computers outperform classical computers on specific tasks.
A major breakthrough came in 1994 when Peter Shor introduced an algorithm for factoring large numbers, which could break widely used encryption methods like RSA and Diffie-Hellman, showing the vast potential of quantum computing. This revelation sparked intense interest in the field. Two years later, in 1996, Lov Grover introduced Grover’s algorithm, which provided a quantum speedup for unstructured search problems. In the same year, Seth Lloyd proved that quantum systems could be simulated without the exponential overhead faced by classical simulations, validating Feynman’s earlier conjecture from 1982.
During the late 1990s and early 2000s, experimental advancements followed these theoretical breakthroughs. Small-scale quantum computers were built using trapped ions and superconductors, and the first two-qubit quantum computer was demonstrated in 1998. This proved that quantum computing was feasible, and subsequent experiments expanded the number of qubits and improved error rates, making the dream of a fully functional quantum computer more tangible. These advancements also hinted at the future development of a quantum internet, where quantum entanglement and secure quantum communication protocols could revolutionize global communication networks.
?
?In 2019, Google AI and NASA announced that they had achieved quantum supremacy with a 54-qubit machine, performing a computation that would be impossible for any classical computer. This claim, though debated within the scientific community, underscored the accelerating progress in quantum computing. Beyond computation, the possibilities for a quantum internet also started to take shape, as quantum networks leveraging entanglement could allow for instantaneous, secure communication across vast distances.
The most recent breakthrough came in December 2023, when physicists reported the first-ever entanglement of individual molecules, a milestone that could have far-reaching implications for both quantum computing and the quantum internet. This development may enable more scalable quantum processors and quantum communication systems, pushing us closer to realizing the vision of a global quantum network.
?Quantum technologies face several critical challenges as they move from theoretical breakthroughs to practical applications. One of the primary obstacles is quantum decoherence, where the delicate quantum states—such as superposition and entanglement—rapidly lose their integrity due to environmental interference. This makes maintaining stable qubits over time a significant challenge, requiring sophisticated error-correction techniques. Another issue is scalability: while small quantum processors with a limited number of qubits have been demonstrated, expanding these systems to handle practical, large-scale computations without a dramatic increase in error rates remains a major hurdle. Additionally, developing quantum hardware that is both reliable and cost-effective poses a significant engineering challenge, as current quantum systems are highly complex and resource-intensive. Interfacing quantum systems with existing classical technologies, particularly in fields like cryptography and communications, also requires overcoming compatibility issues and building a hybrid infrastructure. Finally, there is a pressing need for new algorithms and software optimized for quantum computing to fully realize its potential across industries. Despite these challenges, continued research and collaboration are essential to unlock the transformative power of quantum technologies.
In summary, these milestones—spanning the development of quantum information theory, quantum computing, and the quantum internet—demonstrate the convergence of quantum mechanics and computer science into a revolutionary new field. From cryptography and algorithm discovery to experimental advances in qubit technology and secure quantum communication, the journey from theoretical insights to practical applications has set the stage for transformative advancements in computing and communication. Each stage has brought us closer to a future where quantum technologies reshape industries from cybersecurity to telecommunications. However, these groundbreaking innovations come with significant challenges. Quantum systems are incredibly sensitive to environmental factors, leading to high error rates and the need for complex error-correction mechanisms. Additionally, scaling up quantum processors while maintaining stability remains a major hurdle. Developing the infrastructure for a quantum internet and ensuring interoperability across quantum and classical systems will also demand extensive research and collaboration. Despite these challenges, the potential economic and societal impact of quantum technologies makes overcoming these obstacles a priority for researchers and industries alike.
What is Quantum Technology [2, 3, 4, 5, 6, 7]
Quantum information processing, fundamentally different from classical computing, leverages the unique properties of quantum mechanics—superposition and entanglement. Classical computers rely on classical electrodynamics, where quantum effects are often present but quickly decohere due to environmental interactions, preventing their practical use in computation. In contrast, quantum computers require precise control over coherent quantum systems, and their operations are deeply rooted in linear algebra. In these systems, complex numbers represent probability amplitudes, vectors represent quantum states, and matrices represent operations on those states. Programming a quantum computer involves carefully composing these operations to ensure both theoretical correctness and practical feasibility.
At the core of quantum computing is the qubit, the basic unit of quantum information. Unlike classical bits, which represent either a 0 or 1, qubits can exist in a superposition of both states, mathematically described as a linear combination of |0? and |1?. The coefficients in this combination (α and β) are complex numbers called probability amplitudes, whose squared magnitudes correspond to the likelihood of measuring the qubit in either state. This principle is governed by the Born rule.
As more qubits are added, the system’s state space grows exponentially. For example, a two-qubit system inhabits a four-dimensional space, while three qubits expand into eight dimensions. This rapid growth in state complexity makes it exceedingly difficult for classical computers to simulate quantum systems, as even a modest 100-qubit quantum computer would require storing 2^100 classical values.
In addition to superposition, entanglement is another key feature of quantum computing. Entangled qubits are interconnected in such a way that the state of one instantly influences the state of another, regardless of the physical distance between them. This property underpins many quantum algorithms and provides computational power beyond what is possible with classical systems. However, quantum decoherence—the loss of a qubit’s quantum state due to environmental interaction—remains a significant obstacle, introducing errors into quantum computations. Maintaining the delicate quantum states of qubits requires isolating them in environments with minimal external disturbance, often at extremely low temperatures.
Research is ongoing to build more stable and scalable quantum systems, with technologies such as superconducting qubits and ion traps being developed to extend coherence times and reduce error rates. These innovations are critical to the future of quantum computing, especially as researchers work toward quantum error correction, which is vital for practical, large-scale quantum systems.
Quantum computing offers unparalleled computational speed in solving certain problems, vastly outperforming classical computers. Shor’s algorithm, for instance, demonstrates how quantum computers could factor large numbers exponentially faster than any known classical algorithm, posing a threat to current cryptographic systems. This capability has led to the notion of quantum supremacy, where quantum systems outperform classical ones in specific tasks. Google’s 2019 claim of achieving quantum supremacy with a 54-qubit machine marked a significant milestone, although its practical applications remain limited due to the experimental nature of the technology.
In industries such as pharmaceuticals, chemistry, and machine learning, quantum computers could revolutionize processes by performing complex simulations and analyses far more efficiently than classical machines. For example, they could simulate molecular interactions for drug discovery or optimize catalysts for environmental processes. Machine learning models could also benefit from quantum speedup, processing vast datasets much more effectively.
However, for quantum computing to become widely applicable, technical challenges like error correction and scalability must be addressed. Companies like IBM, Google, and Microsoft are at the forefront of these efforts, with IBM aiming to develop systems with hundreds of qubits by the 2030s. Hybrid systems, which combine classical and quantum computing, are already emerging. These systems allow quantum processors to handle specific tasks, like simulations, while classical processors manage the simpler parts of computations.
Beyond quantum computing, another transformative concept is the quantum internet. The quantum internet is envisioned as a network that allows for the secure transmission of quantum information between distant quantum devices. It would extend the unique advantages of quantum mechanics—such as entanglement and superposition—into communication systems, enabling ultra-secure information exchange and distributed quantum computing.
At the heart of the quantum internet is quantum entanglement, which enables quantum teleportation—the instantaneous transfer of quantum states between entangled particles. This allows for secure communication protocols, such as quantum key distribution (QKD), which uses the no-cloning theorem to ensure that eavesdropping can be detected. QKD has already seen early implementations in secure communication channels, providing unparalleled security by using quantum states to encrypt data.
In a quantum internet, quantum repeaters—specialized devices that extend the range of entanglement over long distances—would play a key role. These repeaters would overcome the challenges posed by quantum decoherence and loss in optical fibers, enabling entanglement-based communication over large distances without significant degradation of the quantum states.
The quantum internet would enable distributed quantum computing, where quantum processors in different locations collaborate on solving large-scale problems. Instead of relying on one massive quantum computer, tasks could be divided among multiple quantum devices, each performing part of the computation. This distributed approach would offer several advantages, including enhanced fault tolerance and the ability to leverage quantum resources in different geographical locations.
In practical terms, the quantum internet could revolutionize industries that rely on secure data transmission and complex simulations. Financial institutions and governments could use quantum networks for secure communication, safeguarding sensitive information against future quantum attacks. In telecommunications, quantum networks could support high-capacity, low-latency connections for real-time data processing and transmission. Scientific research could benefit from collaborative quantum computing efforts, accelerating advances in fields like materials science, climate modeling, and artificial intelligence.
Despite its potential, the quantum internet is still in its early stages of development. Major research initiatives, like those led by China, Europe, and the United States, are exploring the technologies needed to build global quantum networks. China, in particular, has demonstrated significant progress, successfully launching a quantum communication satellite and conducting quantum-encrypted video calls between continents.
As quantum technologies advance, both quantum computing and the quantum internet are poised to redefine the future of information processing and communication. The combination of these two technologies will enable a new era of computing power, security, and efficiency, with widespread implications across industries. While the journey toward a fully functional quantum internet is still in progress, the foundational research being conducted today will pave the way for the quantum-enabled world of tomorrow.
One of the most immediate and transformative applications of quantum technology is in the field of quantum cryptography. Classical cryptography relies on the computational difficulty of certain mathematical problems, such as factoring large numbers (used in RSA encryption). However, with Shor’s algorithm, a quantum computer could efficiently factor large integers, breaking widely used encryption methods and rendering much of current cryptography insecure. This presents a critical challenge to data security in the digital world.
Quantum cryptography, however, offers a solution. The most well-known quantum cryptographic technique is Quantum Key Distribution (QKD), specifically the BB84 protocol, developed by Charles Bennett and Gilles Brassard in 1984. In QKD, a cryptographic key is exchanged using quantum states, typically photons. Because measuring quantum states disturbs them, any attempt to eavesdrop on the key exchange can be immediately detected, ensuring that the communication remains secure. Unlike classical cryptography, which is vulnerable to advances in computational power (including future quantum computers), quantum cryptography provides information-theoretic security—meaning it is secure against any computational attack, regardless of the attacker's resources.
QKD systems are already being implemented for secure communication, particularly in industries such as banking and government where data security is paramount. China, for example, has launched the world’s first quantum communication satellite, Micius, which successfully demonstrated QKD between ground stations across vast distances, including between continents. These early implementations are laying the groundwork for the broader use of quantum cryptography in the future quantum internet.
The no-cloning theorem, which is fundamental to quantum mechanics, guarantees that quantum states cannot be perfectly copied, providing an inherent level of security that classical systems cannot match. This makes quantum cryptography particularly valuable in protecting sensitive communications, from military operations to financial transactions.

Mathematics Driving Quantum Computing
Quantum computing is grounded in a variety of mathematical fields that provide the foundation for its theoretical and practical framework. At its core, linear algebra, Saturday with Math Aug 17th, ?plays a crucial role, as quantum states are represented as vectors in complex vector spaces, also known as Hilbert spaces, and quantum operations (gates) are described using unitary matrices. Matrix operations such as multiplication, tensor products, and eigenvalue decomposition, discussed in Saturday with Math Aug 17th and Sept 7th, ?are fundamental in modeling the evolution of quantum systems. In this context, the Bra-Ket notation, introduced by Dirac, is widely used to represent quantum states and their duals, providing a concise way to express quantum operations.
Alongside linear algebra, complex numbers are pivotal in quantum mechanics. Quantum states are described by probability amplitudes, which are complex numbers whose magnitudes correspond to the probabilities of various outcomes when measurements are made. The interference between quantum states, a key quantum phenomenon, depends on the phase relationships between these complex amplitudes.
Probability theory, discussed in Saturday with Math Aug 31st, is also central to quantum computing, given that the outcomes of quantum measurements are inherently probabilistic. The probabilities of different outcomes are calculated as the squares of the magnitudes of probability amplitudes. Moreover, the concept of expectation values, which comes from probability theory, is used to predict the average outcome of repeated measurements on quantum systems.
Group theory enters the picture through its ability to describe symmetries in quantum systems and the structure of quantum gates. Many quantum gates, such as Pauli matrices or the Hadamard gate, are elements of certain mathematical groups, like the special unitary group SU(2), which represents rotations on the Bloch sphere, a geometric representation of a qubit's state.
Another critical mathematical tool is Fourier analysis, discussed in Saturday with Math May 25th and Jul 27th?, which appears in quantum computing through the Quantum Fourier Transform (QFT). This is a quantum analog of the classical Fourier transform and is used in algorithms such as Shor’s algorithm, which solves problems like integer factorization by exploiting periodicity in quantum systems. More broadly, Fourier analysis is essential in quantum mechanics, where wavefunctions can be represented as superpositions of different frequencies, capturing the probabilistic nature of quantum states.
The study of functional analysis is closely related to the structure of quantum states, as quantum mechanics takes place within the framework of Hilbert spaces. These are vector spaces endowed with an inner product that allows for the definition of concepts such as orthogonality and norm, which are used to describe quantum states, observables, and dynamics. Quantum observables, such as position or momentum, and quantum gates are modeled as operators acting on these spaces, with their eigenvalues corresponding to measurable physical quantities.
In addition to these core areas, information theory contributes, discussed in Saturday with Math Jul 13th,? significantly to quantum computing, particularly through the concept of quantum entropy, which generalizes classical entropy to quantum systems using von Neumann entropy. Quantum information theory also investigates quantum channels, which describe how quantum information is transmitted and degraded in noisy environments, and plays a key role in quantum error correction and communication protocols.
More advanced fields like topology are explored in topological quantum computing, a theoretical framework that uses the topological properties of quantum states to achieve fault-tolerant quantum computation. This approach leverages the braiding of anyons—particles that exist in two-dimensional systems with unique properties—to protect quantum information from local disturbances.
Computational complexity theory also intersects with quantum computing by defining new complexity classes, such as BQP (Bounded-error Quantum Polynomial time), which capture the class of problems efficiently solvable by quantum computers. This field explores the fundamental question of which problems are more efficiently solved on a quantum computer compared to a classical one.
Finally, number theory, discussed in Saturday with Math Jun 1st, plays an important role in quantum algorithms, particularly in Shor’s algorithm, which uses properties of modular arithmetic and periodic functions to factor large numbers exponentially faster than classical algorithms, showcasing the immense potential of quantum computing.
Together, these mathematical fields form a comprehensive foundation for quantum computing, enabling us to understand and design quantum systems, operations, and algorithms that promise to revolutionize computation.
Equation in Focus
The equation in focus is the Schr?dinger equation, formulated by Erwin Schr?dinger in 1925, is a fundamental equation in quantum mechanics that describes how the wave function of a quantum system evolves over time. It revolutionized physics by providing a probabilistic framework for predicting the behavior of particles at the quantum level, where classical mechanics fails. The equation relates to the wave-particle duality, explaining how particles like electrons exhibit both wave-like and particle-like properties. It introduced key concepts like superposition and quantum tunneling, which have profound implications in fields such as quantum chemistry and modern electronics. The equation successfully predicts the discrete energy levels of atoms, providing a theoretical basis for the observed spectra. Although non-relativistic, it serves as the foundation for understanding a wide range of quantum phenomena. Extensions like the Dirac equation are used for relativistic cases, further advancing the study of quantum systems. The Schr?dinger equation remains central to modern physics, underpinning both theoretical and practical advancements.
About Schr?dinger [17]
Erwin Schr?dinger (1887–1961) was a distinguished Austrian physicist who played a crucial role in the development of quantum mechanics. He is best known for formulating the Schr?dinger equation, which describes how the quantum state of a physical system changes over time. For this achievement, he shared the 1933 Nobel Prize in Physics with Paul Dirac. Schr?dinger also coined the term "quantum entanglement" and introduced the famous thought experiment "Schr?dinger's cat," which highlights the paradoxes of quantum theory. Throughout his career, he made significant contributions to various fields, including statistical mechanics, thermodynamics, color theory, and theoretical biology, most notably through his work "What is Life?" which influenced future research in genetics. Schr?dinger also had a profound interest in philosophy, particularly in Eastern thought and the nature of consciousness.
About Deutsch [18]
David Deutsch (born 1953) is a British physicist and one of the pioneers of quantum computing. He formulated the concept of a quantum Turing machine, laying the groundwork for quantum computation, and developed the Deutsch-Jozsa algorithm, which demonstrated the potential for quantum algorithms to vastly outperform classical ones. Deutsch is a proponent of the many-worlds interpretation of quantum mechanics, contributing significantly to the philosophical and theoretical understanding of the field. He is also known for his work on Constructor Theory, which seeks to generalize quantum computation principles to all physical processes. Deutsch has written influential books, including The Fabric of Reality and The Beginning of Infinity, where he explores the philosophical implications of quantum mechanics and the nature of knowledge creation.
