Why Quantum Computers Are a Risk

Quantum computers represent a significant threat to corporations and software development companies due to their potential to break current encryption methods. Leveraging the principles of quantum mechanics, these computers can process complex calculations at speeds unattainable by classical computers. This capability could render existing cybersecurity measures obsolete, exposing sensitive corporate and customer data to new vulnerabilities. In short, data at rest and in transit can be decrypted in a short period of time. As quantum computing technology continues to advance, it's imperative for businesses to reassess and fortify their cybersecurity strategies to safeguard against these emerging threats.

Current State of the Industry

The current state of the art in quantum computing is marked by significant advancements and a dynamic landscape dominated by both established tech giants and emerging start-ups. The field is characterized by the development of five major hardware technologies: photonic networks, superconducting circuits, spin qubits, neutral atoms, and trapped ions. Each of these technologies has its own set of challenges and advantages, contributing to the diversity in the quantum computing ecosystem.

The hardware segment of quantum computing is known for its high complexity and risk, necessitating substantial capital and specialized knowledge. This has led to the dominance of technology giants who have been in the market for about a decade, with a focus on superconducting qubits. However, the past four years have seen a surge in investment and growth among start-ups specializing in ion traps, neutral atoms, and photonic qubits, with companies like IonQ, PASQAL, and PsiQuantum leading the charge.

Despite these advancements, the quantum computing market is still in its infancy, with most products, particularly in the systems software segment, being in the prototype phase. This nascent stage is further evidenced by the limited number of working use cases and the challenges posed by existing hardware patents, which have somewhat hindered the creation of new applications start-ups. Nonetheless, the quantum computing value chain, particularly the equipment and components segment, has reached a level of maturity, generating significant revenue through sales to universities, research institutes, and technology companies. This segment remains open to specialized players, suggesting a continued evolution and expansion of the quantum computing market in the coming years.

Quantum Cyber Attacks Already In Progress

China and other nation-state actors have been proactively involved in quantum computing and quantum cryptography, illustrating a potential threat to global cybersecurity. For instance, in 2021, Chinese scientists established an integrated quantum network, facilitating quantum key distribution across vast distances. By 2022, a Chinese team made significant strides by cracking 48-bit RSA encryption using a 10-qubit quantum computer-based system, hinting at the potential to breach more robust 2048-bit RSA encryption in the future. By 2023, China emerged as one of the few nations, alongside the United States and Canada, capable of delivering a commercially viable quantum computer, developed indigenously.

This progression underscores a critical concern: nation-state actors like China might be capturing and storing encrypted data and databases today with the anticipation of decrypting them using quantum computing capabilities in the future. Even though the data might become slightly outdated by the time it is decrypted, its strategic value, particularly in terms of intellectual property, state secrets, and personal information, could be immense. This preemptive "harvest now, decrypt later" strategy poses a silent but potentially devastating threat, indicating that many organizations might already be under attack without their knowledge.

Quantum Encryption and Quantum Communication

As the nature of this technology and the associated threats become more widespread, you are going to start hearing more and more about quantum encryption and quantum communication (QComms).

Quantum encryption and quantum communication, while closely related, serve distinct purposes within the realm of quantum technologies. Quantum computing leverages the principles of quantum mechanics to achieve exponential performance improvements for specific applications, potentially opening up entirely new computing territories. This advancement includes the development of quantum encryption methods, which use quantum principles to secure data in a way that is theoretically immune to decryption by conventional and quantum computers alike. Quantum encryption is seen as a subset of quantum computing where the focus is on utilizing quantum properties to create secure cryptographic protocols.

On the other hand, QComms involve the secure transfer of quantum information across space, often using particles like photons. The cornerstone of quantum communication is quantum key distribution (QKD), a method for secure communication that enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages. It ensures the security of communications against eavesdropping, even by adversaries with unlimited computing power, including quantum computers. This distinction highlights the broader application of quantum communication in establishing secure networks and links, beyond the sole purpose of encrypting information, which is the primary focus of quantum encryption.

iMessage Is Preparing

Apple has recently introduced a groundbreaking update to iMessage encryption, integrating post-quantum protections dubbed PQ3, which Apple describes as the "most significant cryptographic security upgrade" in the app's history. This new encryption protocol, PQ3, aims to substantially bolster iMessage's security, setting a new standard with what Apple claims is Level 3 security, surpassing all other widely used messaging apps in terms of protocol protections against sophisticated quantum attacks. Despite the fact that fully functional quantum computers have not yet been realized, the anticipation of their eventual development and potential to break current public-key encryption algorithms has prompted such preemptive measures. The PQ3 protocol, powered by the "post quantum secure" Kyber algorithm developed by NIST researchers, is designed to guard against "harvest now, decrypt later" attacks, where encrypted data is collected now in hopes of decrypting it with future quantum technology. This update places Apple at the forefront of post-quantum encryption, alongside other tech giants like Google, who are also working on similar standards to protect against future quantum threats. Security experts have lauded the update, with cryptography professor Matthew Green acknowledging PQ3 as a significant improvement, even if it might seem like overkill given the current state of quantum computing and the rarity of key compromise.

Prepare Yourself

To safeguard against quantum cybersecurity threats, corporations must proactively adopt quantum-resistant cryptography. This entails transitioning to cryptographic algorithms that remain secure in the face of quantum computing attacks.
