10.9.2 Quantum Properties and Computing
The quantum properties that are used in quantum computations are superposition,
entanglement and interference. Superposition is the combination of multiple independent quantum states. Due to the superposition of states, a Qubit can be 0 and 1 state
simultaneously. Entanglement is a quantum property by which multiple quantum
states can be correlated with one another. Interference of quantum states happens
due to phase of wave function of states. In computing, superposition of quantum
states in Qubits allows parallel processing, unlike a binary computer, where parallel
processing of information is not possible. Entanglement and interference are used in
computing. Entangled Qubits can be used in error fixing.
