Teleportation of an atomic momentum state
(American Physical Society, 2003)
In this paper, we propose a scheme for teleportating a superposition of atomic center-of-mass momentum states to a superposition of the cavity field using quantum controlled-NOT gate via atomic scattering in the Bragg ...
Reversing entanglement change by a weak measurement
(American Physical Society, 2010)
Entanglement of a system changes due to interactions with the environment. A typical type of interaction is amplitude damping. If we add a detector to monitor the environment and only select the no-damping outcome, this ...
Reply to "Comment on 'Quantum search protocol for an atomic array' "
(American Physical Society, 2002)
Our quantum search protocol indicates that entanglement is not required for rootN speedup. We also reemphasize the quantum error correction mechanism in our scheme.
Single atom as a macroscopic entanglement source
(American Physical Society, 2006)
We discuss the generation of a macroscopic entangled state in a single atom cavity-QED system. The three-level atom in a cascade configuration interacts dispersively with two classical coherent fields inside a doubly ...
Role of noise operators on two-photon correlations in an extended coherent Raman medium
(American Physical Society, 2007)
An extended medium driven in a double Raman configuration generates Stokes and anti-Stokes fields that are described by coupled parametric oscillator equations with solutions that depend on input boundary operators and ...
