On an operator Kantorovich inequality for positive linear maps
Minghua Lin
We improve the operator Kantorovich inequality as follows: Let be a positive operator on a Hilbert space with . Then for every unital positive linear map , \…
Shape from sound: toward new tools for quantum gravity
David Aasen, Tejal Bhamre, Achim Kempf
To unify general relativity and quantum theory is hard in part because they are formulated in two very different mathematical languages, differential geometry and functional analys…
Generating polarization-entangled photon pairs using cross-spliced birefringent fibers
Evan Meyer-Scott, Vincent Roy, Jean-Philippe Bourgoin +3
We demonstrate a novel polarization-entangled photon-pair source based on standard birefringent polarization-maintaining optical fiber. The source consists of two stretches of fibe…
Vanishing quantum discord is not necessary for completely-positive maps
Aharon Brodutch, Animesh Datta, Kavan Modi +2
The description of the dynamics of a system that may be correlated with its environment is only meaningful within the context of a specific framework. Different frameworks rely upo…
Down-conversion source of positively spectrally correlated and decorrelated photon pairs at telecom wavelength
Thomas Lutz, Piotr Kolenderski, Thomas Jennewein
The frequency correlation (or decorrelation) of photon pairs is of great importance in long-range quantum communications and photonic quantum computing. We experimentally character…
Novel High-Speed Polarization Source for Decoy-State BB84 Quantum Key Distribution over Free Space and Satellite Links
Zhizhong Yan, Evan Meyer-Scott, Jean-Philippe Bourgoin +5
To implement the BB84 decoy-state quantum key distribution (QKD) protocol over a lossy ground-satellite quantum uplink requires a source that has high repetition rate of short lase…
