Reversing the weak measurement of an arbitrary field with finite photon number
(American Physical Society, 2009)
For an arbitrary field with finite photon number inside a leaky cavity, we show that the null-result measurement can be conditionally reversed, using either multiple atoms or a multilevel atom. Even with photons detected, ...
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 ...
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 ...
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 ...
