Quantum Computing

Quantum computing is a field that uses quantum mechanics to solve complex problems faster than classical computers. It combines aspects of computer science, physics, and mathematics.

Quantum computing is an emergent field of cutting-edge computer science harnessing the unique qualities of quantum mechanics to solve problems beyond the ability of even the most powerful classical computers.

Four key principles of quantum mechanics

Understanding quantum computing requires understanding these four key principles of quantum mechanics:

• Superposition:?Superposition is the state in which a quantum particle or system can represent not just one possibility, but a combination of multiple possibilities.

• Entanglement: Entanglement is the process in which multiple quantum particles become correlated more strongly than regular probability allows.

• Decoherence: Decoherence is the process in which quantum particles and systems can decay, collapse or change, converting into single states measurable by classical physics.

• Interference: Interference is the phenomenon in which entangled quantum states can interact and produce more and less likely probabilities.
• Key principles of quantum computing

When discussing quantum computers, it is important to understand that quantum mechanics is not like traditional physics. The behaviors of quantum particles often appear to be bizarre, counterintuitive or even impossible. Yet the laws of quantum mechanics dictate the order of the natural world.

Describing the behaviors of quantum particles presents a unique challenge. Most common-sense paradigms for the natural world lack the vocabulary to communicate the surprising behaviors of quantum particles.

To understand quantum computing, it is important to understand a few key terms:

• Superposition
• Entanglement
• Decoherence
• Interference.
