Decoherence, Continuous Observation, and Quantum Computing: A Cavity QED Model
Thomas Pellizzari, S. A. Gardiner, J. I. Cirac, P. Zoller · Physical Review Letters · 1995
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.
