Topological color codes on Union Jack lattices: a stable implementation of the whole Clifford group
(American Physical Society, 2010)
We study the error threshold of topological color codes on Union Jack lattices that allow for the full implementation of the whole Clifford group of quantum gates. After mapping the error-correction process onto a statistical ...
Observation of picosecond superfluorescent pulses in rubidium atomic vapor pumped by 100-fs laser pulses
(American Physical Society, 2010)
We study the superfluorescence (SF) from a gas of rubidium atoms. The atoms of a dense vapor are excited to the 5D state from the 5S state by a two-photon process driven by 100-fs laser pulses. The atoms decay to the 6P ...
Coherent control of the Goos-Hanchen shift
(American Physical Society, 2010)
The behavior of the Goos-Hanchen (GH) shifts in the reflected and transmitted light beam which is incident on a cavity containing an intracavity medium of three-level or four-level atoms with electromagnetically induced ...
Effects of noise and parameter deviations in a bichromatic Raman white light cavity
(American Physical Society, 2010)
We analyze the effects of noise and parameter deviations in a bichromatic Raman type white light cavity, with potential applications in precision measurements. The results show that the dispersion variation induced by ...
Quantum anomalous Hall effect with cold atoms trapped in a square lattice
(American Physical Society, 2010)
We propose an experimental scheme to realize the quantum anomalous Hall effect in an anisotropic square optical lattice which can be generated from available experimental setups of double-well lattices with minor modifications. ...
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 ...
Glucose concentration measured by the hybrid coherent anti-Stokes Raman-scattering technique
(American Physical Society, 2010)
We investigate the possibility of using a hybrid coherent anti-Stokes Raman scattering technique for noninvasive monitoring of blood glucose levels. Our technique combines instantaneous coherent excitation of several ...
Control of the Lamb shift by a driving field
(American Physical Society, 2010)
A unitary transformation approach is used to study the energy level shift of the atom coupled to both a vacuum electromagnetic field and a driving laser. The Lamb shift of the energy levels is shown to depend on the Rabi ...
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 ...
