Operator-orderization programme for quantum gates of continuum state

Due to the non-commutativity of fundamental operators of quantum mechanics, the classical computer can do nothing with operation of quantum gates, in this paper, we propose operator-orderization programme, so that using classical computers we can derive quantum unitary gates from the corresponding classical transformation, as examples, we employ operator-orderization programme to derive Squeezing gate, Not gate, Swap gate and Hadamard gate on classical computers. We predict that our this scheme may have profound applications in the near future.
