Abstract

A brief introduction to the basics of quantum computation is given. We present a generic physical model of quantum computer hardware and compare ideal and physically realizable quantum computers. The physical model is then used to simulate quantum computers hardware on a Quantum Computer Emulator (QCE) . We address the issue of reliable quantum computation on physically realizable hardware using the QCE and Grover's database search algorithmas an example . We shown that in the absence of dissipation non-ideal, physically realizable quantum computers operate in a regime of extreme sensitivity. This high sensitivity reflects itself in problems of programming quantum computers such that they perform correct calculations . The role of dissipation as a stabilizing process will be discussed..
