Using Conditional Measurements to Combat Decoherence

Quantum Physics 2011-04-15 v1

Abstract

With the help of some remarkable examples, it is shown that conditional measurements performed on two-level atoms just after they have interacted with a resonant cavity field mode are able to recover the coherence of number-state superpositions, which is lost due to dissipation.
