How often is a random quantum state k-entangled?
Stanislaw J. Szarek, Elisabeth Werner, Karol Zyczkowski
The set of trace preserving, positive maps acting on density matrices of size d forms a convex body. We investigate its nested subsets consisting of k-positive maps, where k=2,...,…

Atomic Dipole Traps with Amplified Spontaneous Emission: A Proposal
Jean-François Clément, Véronique Zehnlé, Jean Claude Garreau +1
We propose what we believe to be a novel type of optical source for ultra-cold atomic Far Off-Resonance optical-dipole Traps (FORTs). The source is based on an Erbium Amplified Spo…

Hastings' additivity counterexample via Dvoretzky's theorem
Guillaume Aubrun, Stanislaw Szarek, Elisabeth Werner
The goal of this note is to show that Hastings' counterexample to the additivity of minimal output von Neumann entropy can be readily deduced from a sharp version of Dvoretzky's th…
