Journal ArticleDOI
Large-alphabet quantum key distribution using energy-time entangled bipartite States.
TL;DR: Binned, high-resolution timing measurements are used to generate a large-alphabet key with over 10 bits of information per photon pair, albeit with large noise.
Journal ArticleDOI
Einstein-Podolsky-Rosen steering inequalities from entropic uncertainty relations
James Schneeloch,Curtis J. Broadbent,Stephen P. Walborn,Eric G. Cavalcanti,Eric G. Cavalcanti,John C. Howell +5 more
TL;DR: In this article, the authors use entropic uncertainty relations to formulate inequalities that witness EPR steering correlations in diverse quantum systems and then use these inequalities to formulate symmetric EPR-steering inequalities using the mutual information.
Journal ArticleDOI
Experimental violation of two-party Leggett-Garg inequalities with semiweak measurements.
TL;DR: The authors generalized the derivation of Leggett-Garg inequalities to systematically treat a larger class of experimental situations by allowing multiparticle correlations, invasive detection, and ambiguous detector results.
Journal ArticleDOI
Genuinely multipartite concurrence of N -qubit X matrices
TL;DR: In this article, an algebraic formula for the concurrence of $N$ qubits in an orthonormal basis matrix is given, and the half-life of the entanglement is proportional to the inverse of the number of qubits.
Journal ArticleDOI
All-optical delay of images using slow light.
TL;DR: Two-dimensional images are delayed in a cesium vapor cell and the transverse phase and amplitude profiles of the images are shown to be preserved, even at very low light levels.
