Quantifying entanglement with probabilities
Markus A. Cirone
We propose a new approach to the problem of defining the degree of entanglement between two particles in a pure state with Hilbert spaces of arbitrary finite dimensions. The centra…

The s-wave implosion and explosion of free particles
I. Bialynicki-Birula, M. A. Cirone, J. P. Dahl +2
A free quantum particle in two dimensions with vanishing angular momentum (s-wave) in the form of a ring-shaped wave packet feels an attractive force towards the center of the ring…

Estimation of quantum channels with finite resources
Markus A. Cirone, Aldo Delgado, Dietmar G. Fischer +3
We investigate the problem of determining the parameters that describe a quantum channel. It is assumed that the users of the channel have at best only partial knowledge of it and…
