Question: what is the difference between a normal computer and a quantum computer?
Answer: Information storage and manipulation is based on “bit”, which is based on voltage or charge; low is 0 and high is 1. ... Conventional computing use binary codes i.e. bits 0 or 1 to represent information. Quantum computing use Qubits i.e. 0, 1 and superposition state of both 0 and 1 to represent information.
