Decoherence, continuous observation, and quantum computing: A cavity QED model
Abstract
We use the theory of continuous measurement to analyze the effects of decoherence on a realistic model of a quantum computer based on cavity QED. We show how decoherence affects the computation, and methods to prevent it.
