Generation of a superposition of multiple mesoscopic states of radiation in a resonant cavity
(American Physical Society, 2005-04-27)
Using resonant interaction between atoms and the field in a high quality cavity, we show how to generate a superposition of many mesoscopic states of the field. We study the quasi-probability distributions and demonstrate ...
Large two-atom two-photon vacuum Rabi oscillations in a high-quality cavity
(American Physical Society, 2004-10-11)
We predict a large cooperative effect involving two-atom two-photon vacuum Rabi oscillations in a high-quality cavity. The two-photon emission occurs as a result of simultaneous deexcitation of both atoms with two-photon ...
dc-field-induced enhancement and inhibition of spontaneous emission in a cavity
(American Physical Society, 2004-08-20)
We demonstrate how spontaneous emission in a cavity can be controlled by the application of a dc field. The method is specially suitable for Rydberg atoms. We present a simple argument based on Stark shifts for the control ...
Mesoscopic superposition of states with sub-Planck structures in phase space
(American Physical Society, 2004-11-11)
We propose the cavity quantum electrodynamics method, using dispersive interaction between atoms and a high-quality cavity to realize the mesoscopic superposition of coherent states that would exhibit sub-Planck structures ...
Realization of quantum-mechanical weak values of observables using entangled photons
(American Physical Society, 2007-03-12)
We present a scheme for realization of quantum-mechanical weak values of observables using entangled photons produced in parametric down-conversion. We consider the case when the signal and idler modes are respectively in ...
Quantum random walk of the field in an externally driven cavity
(American Physical Society, 2005-09-16)
Using a resonant interaction between atoms and the field in a high-quality cavity, we show how to realize quantum random walks as proposed by Aharonov et al. [Phys. Rev. A 48, 1687 (1993)]. The atoms are driven strongly ...
