Quantum study of information delay in electromagetically induced transparency
Magnus T. L. Hsu, Gabriel Hetet, Oliver Glockl +4
Using electromagnetically induced transparency (EIT), it is possible to delay and store light in atomic ensembles. Theoretical modelling and recent experiments have suggested that…
Erratum : Squeezing and entanglement delay using slow light
G. Hetet, A. Peng, M. T. Johnsson +5
An inconsistency was found in the equations used to calculate the variance of the quadrature fluctuations of a field propagating through a medium demonstrating electromagnetically…
A quantum study of multi-bit phase coding for optical storage
Magnus T. L. Hsu, Vincent Delaubert, Warwick P. Bowen +3
We propose a scheme which encodes information in both the longitudinal and spatial transverse phases of a continuous-wave optical beam. A split detector-based interferometric schem…
Can optical squeezing be generated via polarization self-rotation in a thermal vapour cell?
M. T. L. Hsu, A. Dantan, J. Cviklinski +9
The traversal of an elliptically polarized optical field through a thermal vapour cell can give rise to a rotation of its polarization axis. This process, known as polarization sel…
Continuous-Variable Spatial Entanglement for Bright Optical Beams
Magnus T. L. Hsu, Warwick P. Bowen, Nicolas Treps +1
A light beam is said to be position squeezed if its position can be determined to an accuracy beyond the standard quantum limit. We identify the position and momentum observables f…
Optimum Small Optical Beam Displacement Measurement
Magnus T. L. Hsu, Vincent Delaubert, Ping Koy Lam +1
We derive the quantum noise limit for the optical beam displacement of a TEM00 mode. Using a multimodal analysis, we show that the conventional split detection scheme for measuring…
