Natural Limitations of Quantum Computing

It is a basic principle of quantum computing to leave the quantum computer to itself without any outside intervention while processing prepared states of data(prepared according to quantum rules).Accordingly ,we must probe the micro world replacing all the components of the theoretical quantum algorithm,including the necessary time ticks, with events of the micro world.This amalgamation with the micro world provides a guarantee that the quantum processing will be totally isolated from the outside world.The whole theoretical quantum algorithm will be immersed in the micro world and become part of it.
