Reversing the weak measurement of an arbitrary field with finite photon number
(American Physical Society, 2009)
For an arbitrary field with finite photon number inside a leaky cavity, we show that the null-result measurement can be conditionally reversed, using either multiple atoms or a multilevel atom. Even with photons detected, ...
Entanglement criteria and nonlocality for multimode continuous-variable systems RID B-8901-2008
(American Physical Society, 2009)
We demonstrate how to efficiently derive a broad class of inequalities for entanglement detection in multimode continuous variable systems. The separability conditions are established from partial transposition (PT) in ...
