We have proposed new superconducting theory based on Spin-Vortex Induced Loop Current(SVILC). This is the nano-sized loop current on CuO2 plane and it is available for qubit of quantum computer. This is very promising candidate for physical realization of quantum computer. It can demonstrate 1 and 2- qubit gate very rapidly. And by external current feeding as a coupler between two currents as single qubit may enable us to fabricate the system with 100 qubit. In this session I introduce the result of numerical simulation of Shor’s algorithm on 4 qubit system. In addition I discuss the result of calculation of Master equation of the noise induced by external current.
