Entangled radiation via a Raman-driven quantum-beat laser
(American Physical Society, 2009)
We propose a scheme for the entanglement generation of two cavity modes using a four-level Raman-driven quantum-beat laser (QBL). The atomic coherence is generated by a Raman-type two-photon process. Two different sufficient ...
Probing the quantum commutation rules through cavity QED
(American Physical Society, 2008)
We propose a cavity QED-based scheme to observe the noncommutativity between the creation and annihilation operators. By conditional measurement after the atom-field interaction in a cavity, it is possible to achieve a ...
Lamb shift due to surface plasmon polariton modes
(American Physical Society, 2008)
The Lamb shift of a hydrogen atom due to the surface plasmon polariton (SPP) modes is calculated and we observe both band edge and surface enhancement. The atom sits inside a thin metal slab which is sandwiched by two ...
Quantum teleportation of four-dimensional qudits
(American Physical Society, 2010)
A protocol for the teleportation of arbitrary quantum states of four-dimensional qudits is presented. The qudit to be teleported is encoded in the combined state of two ensembles of atoms placed in a cavity at the sender's ...
Controllable optical switch using a Bose-Einstein condensate in an optical cavity
(American Physical Society, 2011)
The optical bistability of an ultracold atomic ensemble located in a small-volume ultrahigh-finesse optical cavity is investigated. We find that a transverse pumping field can be used to control the bistable behavior of ...
