Entanglement by linear SU(2) transformations: generation and evolution of quantum vortex states
(Journal of Physics A: Mathematical and General, 2006-07-31)
We consider the evolution of a two-mode system of bosons under the action of a Hamiltonian that generates linear SU(2) transformations. The Hamiltonian is generic in that it represents a host of entanglement mechanisms, ...
Extreme subwavelength atom localization via coherent population trapping
(IOP Publishing, 2006-09-06)
We demonstrate an atom localization scheme based on monitoring of the atomic coherences. We consider atomic transitions in a Lambda configuration where the control field is a standing-wave field. The probe field and the ...
Nonclassical correlation of polarisation entangled photons in a biexciton-exciton cascade
(IOP Publishing, 2008-11-10)
We develop a theoretical model to study the Intensity-Intensity correlation of polarisation entangled photons emitted in a biexciton-exciton cascade. We calculate the degree of correlation and show how polarisation ...
