Reconstruction of a multimode entangled state using a two-photon phase-sensitive linear amplifier
(American Physical Society, 2003)
We propose a model for the measurement of an arbitrary multimode entangled state of the cavity field using two-photon correlated emission laser. We consider two cases: (a) The modes have different frequencies and are ...
Continuous-variable entanglement in a correlated spontaneous emission laser
(American Physical Society, 2005)
We discuss the generation and evolution of entangled light in a correlated spontaneous emission laser. The master equation for the two-mode field in a cavity is derived and solved analytically. The time-dependent characteristic ...
Quantum disentanglement eraser: A cavity QED implementation
(American Physical Society, 2004)
A possible experimental scheme of the Garisto-Hardy disentanglement eraser based on a cavity QED system is presented. This scheme can be used for a delayed choice quantum eraser. It also allows us to acquire single-qubit ...
Coherence-induced entanglement
(American Physical Society, 2005)
We show how atomic coherence can lead to entanglement between two thermal fields at a temperature T. We first show that the passage of a three-level atom in V configuration without coherence cannot create entanglement. ...
