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 ...
Comment on "Spin and statistics in nonrelativistic quantum mechanics: The spin-zero case"
(American Physical Society, 2003)
We emphasize that there is no spin-statistics connection in nonrelativistic quantum mechanics. In several recent papers [including Phys. Rev. A 67, 042102 (2003)], quantum mechanics is modified so as to force a spin-statistics ...
Measurement of the separation between atoms beyond diffraction limit RID A-5077-2009
(American Physical Society, 2006)
Precision measurement of small separations between two atoms or molecules has been of interest since the early days of science. Here, we discuss a scheme which yields spatial information on a system of two identical atoms ...
Atom localization and center-of-mass wave-function determination via multiple simultaneous quadrature measurements RID A-5077-2009
(American Physical Society, 2007)
We discuss localization and center-of-mass wave-function measurement of a quantum particle using multiple simultaneous dispersive interactions of the particle with different standing-wave fields. In particular, we consider ...
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 ...
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 ...
Quantum electrodynamics of accelerated atoms in free space and in cavities
(American Physical Society, 2006)
We consider a gedanken experiment with a beam of atoms in their ground state that are accelerated through a single-mode cavity. We show that taking into account of the "counterrotating" terms in the interaction Hamiltonian ...
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 ...
