A Unified Picture of Decoherence Control
arXiv:quant-ph/0501109 · doi:10.1016/j.chemphys.2005.07.010
Abstract
The different methods of reducing decoherence in quantum devices are discussed from the unified point of view based on the energy conservation principle and the concept of forbidden transitions. Minimal decoherence model, "bang-bang" techniques, Zeno effect and decoherence-free subspaces and subsystems are studied as particular examples.
