Schmidt number witnesses and bound entanglement
Anna Sanpera, Dagmar Bruss, Maciej Lewenstein
The Schmidt number of a mixed state characterizes the minimum Schmidt rank of the pure states needed to construct it. We investigate the Schmidt number of an arbitrary mixed state…
Separability and distillability in composite quantum systems -a primer-
M. Lewenstein, D. Bruss, J. I. Cirac +5
Quantum mechanics is already 100 years old, but remains alive and full of challenging open problems. On one hand, the problems encountered at the frontiers of modern theoretical ph…
Generation and evolution of vortex-antivortex pairs in Bose-Einstein condensates
J. -P. Martikainen, K. -A. Suominen, L. Santos +2
We propose a method for generating and controlling a spatially separated vortex--antivortex pair in a Bose-Einstein condensate trapped in a toroidal potential. Our simulations of t…
