to perform operations on data.[1] Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits)‚ each of which is always in one of two definite states (0 or 1)‚ quantum computation uses qubits (quantum bits)‚ which can be in superpositionsof states. A theoretical model is the quantum Turing machine‚ also known as the universal quantum computer. Quantum computers share theoretical similarities with non-deterministic
