Quantum computing
Computer hardware technology that uses quantum mechanics
- A quantum computer is a computer that represents and processes information using quantum states.
- Quantum computations exploit phenomena such as superposition, interference, and entanglement.
- Quantum computers have the potential to complete some calculations exponentially faster than classical computers.
- For example, a large-scale quantum computer could break widely used encryption schemes and aid physicists in performing physical simulations.
- However, current hardware implementations of quantum computation are largely experimental and suitable for only certain specialized tasks.
