Iterative entanglement distillation for finite resources
Stefan Probst-Schendzielorz, Thorsten Bschorr, Matthias Freyberger
We discuss a specific entanglement distillation scheme under the constraint of finite samples of entangled qubit pairs. It is shown that an iterative process can be explicitly form…

Wave packet dynamics and factorization of numbers
Holger Mack, Marc Bienert, Florian Haug +3
We connect three phenomena of wave packet dynamics: Talbot images, revivals of a particle in a box and fractional revivals. The physical origin of these effects is deeply rooted in…

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…
