  HISTORY 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

  Why quantum computer Moore’law slowing down in 2020 it is flattened out. Transistor cannot be made smaller due to the laws of Quantum mechanics starts to take over Post silicon era
