Journal ArticleDOI
Distinguishability of Gaussian states in quantum cryptography using postselection
TL;DR: It is shown that the two mixed symmetric Gaussian states (where the various components have the same real part) never give an eavesdropper more information than the two pureGaussian states.
Journal ArticleDOI
Continuous variable polarization entanglement, experiment and analysis
TL;DR: In this article, Duan et al. generate and characterise continuous variable polarization entanglement between two optical beams, and show that using two quadrature entangled pairs it is possible to entangle three orthogonal Stokes operators between a pair of beams.
Journal ArticleDOI
Gaussian multipartite quantum discord from classical mutual information
TL;DR: In this paper, the authors examined the quantum discord in the experimentally relevant case when the quantum states are Gaussian and the measurements are restricted to Gaussian measurements, and they performed the optimisation over the measurements to find the Gaussian discord of the bipartite EPR state and tripartite GHZ state.
Journal ArticleDOI
Gradient echo quantum memory in warm atomic vapor.

TL;DR: The basis of the GEM protocol is to absorb the light into an ensemble of atoms that has been prepared in a magnetic field gradient that leads to rephasing of the atomic polarization and thus recall of the stored optical state.
