Abstract
We present a study of quantum computing by engineering nonlocal quantum universal gates. The universal quantum logic gate is based on the interaction of a two-level atom with two modes of the electromagnetic field in a high Q superconducting cavity. The two-level atom acts as a control qubit and the two-mode electromagnetic field serves as a target qubit. Presently available QED experiments make it possible to realize the theoretical suggestion in the laboratory. We check the feasibility of our proposal by calculating the success probability.
