Clean Positive Operator Valued Measures
F. Buscemi, G. M. D'Ariano, M. Keyl +2
In quantum mechanics the statistics of the outcomes of a measuring apparatus is described by a positive operator valued measure (POVM). A quantum channel transforms POVM's into POV…
Some Open Problems in Quantum Information Theory
O. Krueger, R. F. Werner
This article is a snap-shot of a web site, which has been collecting open problems in quantum information for several years, and documenting the progress made on these problems. By…
The optimal cloning of quantum coherent states is non-Gaussian
N. J. Cerf, O. Krueger, P. Navez +2
We consider the optimal cloning of quantum coherent states with single-clone and joint fidelity as figures of merit. Both optimal fidelities are attained for phase space translatio…
Reversible quantum cellular automata
B. Schumacher, R. F. Werner
We define quantum cellular automata as infinite quantum lattice systems with discrete time dynamics, such that the time step commutes with lattice translations and has strictly fin…
The Quantum Monty Hall Problem
G. M. D'Ariano, R. D. Gill, M. Keyl +3
We consider a quantum version of a well-known statistical decision problem, whose solution is, at first sight, counter-intuitive to many. In the quantum version a continuum of poss…
Bell inequalities and Entanglement
Reinhard F. Werner, Michael M. Wolf
We discuss general Bell inequalities for bipartite and multipartite systems, emphasizing the connection with convex geometry on the mathematical side, and the communication aspects…
