Proposal for direct measurement of concurrence via visibility in a cavity QED system
(American Physical Society, 2008)
An experimental scheme is proposed that allows direct measurement of the concurrence of a two-qubit cavity system. It is based on the cavity-QED technology using atoms as flying qubits and relies on the identity of the ...
Manipulation of the Raman process via incoherent pump, tunable intensity, and phase control
(American Physical Society, 2008)
We present a proposal to manipulate the Raman process via incoherent pump, tunable intensity, and phase control of the driving fields. It is found that Raman absorptive peaks can become Raman gain peaks by controlling the ...
One-atom correlated-emission laser RID C-6638-2008
(American Physical Society, 2008)
We study a four-level double-Lambda atomic configuration working as a two photon linear amplifier where two atomic transitions independently interact with cavity mode, while the other transitions are driven by a strong ...
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 ...
Electromagnetically induced transparency inside the laser cavity: Switch between first-order and second-order phase transitions
(American Physical Society, 2008)
We investigate the effect of electromagnetically induced transparency inside a laser cavity. By changing the intensity of an external drive field, we can control the absorption to the laser field. A semiclassical analysis ...
Quantum beat laser as a source of entangled radiation
(American Physical Society, 2008)
We consider a quantum beat laser [Scully and Zubairy, Phys. Rev. A 35 752 (1987)] as a source of entangled radiation. The system essentially consists of three-level atoms inside a doubly resonant cavity such that coherence ...
Optical imaging beyond the diffraction limit via dark states RID A-8711-2009
(American Physical Society, 2008)
We study the possibility of creating spatial patterns having subwavelength size by using the so-called dark states formed by the interaction between atoms and optical fields. These optical fields have a specified spatial ...
Three-qubit phase gate based on cavity quantum electrodynamics
(American Physical Society, 2008)
We describe a three-qubit quantum phase gate which is implemented by passing a four-level atom in a cascade configuration initially in its ground state through a three-mode optical cavity. The three qubits are represented ...
Control of the Goos-Hanchen shift of a light beam via a coherent driving field RID A-4660-2010
(American Physical Society, 2008)
We present a proposal to manipulate the Goos-Hanchen shift of a light beam via a coherent control field, which is injected into a cavity configuration containing the two-level atomic medium. It is found that the lateral ...
