A quantum computer is a calculation gadget that makes steer utilize of quantum mechanical phenomena, for example superposition and trap, to perform operations on information. Quantum machines are distinctive from computerized workstations dependent upon transistors. While computerized workstations need information to be encoded into binary digits (bits), quantum calculation utilizes quantum lands to stand for information and perform operations on the proposed information.

A speculative model is the quantum Turing machine, additionally reputed to be the universal quantum PC. Quantum workstations share speculative similitudes to non-deterministic and probabilistic PCs, such as the capacity to be in more than one state at the same time. The field of quantum processing was first presented by Richard Feynman in 1982. A quantum workstation with twists as quantum bits was in addition defined for utilization as a quantum space-time in 1969.
