Subwavelength optical microscopy in the far field
(American Physical Society, 2011)
We present a procedure for subwavelength optical microscopy. The identical atoms are distributed on a plane and shined with a standing wave. We rotate the plane to different angles and record the resonant fluorescence ...
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 ...
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 ...
