Tunable phase control for subluminal to superluminal light propagation
(American Physical Society, 2004)
We demonstrate tunable control of the group velocity of a weak probe pulse from subluminal to superluminal. The model is an extended Lambda-type system with two extra control fields and an extra energy level. Phase variation ...
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 ...
Cavity QED-based quantum walk
(American Physical Society, 2004)
We discuss a possible experimental scheme for the implementation of a quantum walk. The scheme is based on the passage of an atom inside a high-Q cavity. The chirality is characterized by the atomic states and the displacement ...
Measurement of entangled states via atomic beam deflection in Bragg's regime RID C-6638-2008 RID A-4660-2010
(American Physical Society, 2004)
We propose a scheme for the measurement of joint photon statistics and Wigner function of the entangled field states between two separate cavities. The scheme utilizes the momentum state of the two-level atoms in Bragg's ...
