What is a quantum computer?, A quantum computer is a machine that performs calculations based on the laws of quantum mechanics, which is the behavior of particles at the sub-atomic level. History of Quantum Computing, “I think I can safely say that nobody understands quantum mechanics” – Feynman. 1982 – Feynman proposed the idea of creating machines based on the laws of quantum mechanics instead of the laws of classical physics. 1985 – David Deutsch developed the quantum turing machine, showing that quantum circuits are universal. 1994 – Peter Shor came up with a quantum algorithm to factor very large numbers in polynomial time. 1997 – Lov Grover develops a quantum search algorithm with O(?N) complexity. Quantum Gates, Quantum Gates are similar to classical gates, but do not have a degenerate output. i.e. their original input state can be derived from their output state, uniquely. They must be reversible. This means that a deterministic computation can be performed on a quantum computer only if it is reversible. Luckily, it has been shown that any deterministic computation can be made reversible.(Charles Bennet, 1973).
