The communication of directions using quantum states is a useful laboratory test for some basic facts of quantum information. For a system of spin-1/2 particles there are different quantum states that can encode directions. This information can later be decoded by means of a generalized measurement. In this talk we present the optimal strategies under different assumptions. c 2008 Optical Society of America OCIS codes: (000.1600) Classical and quantum physics; (200.3050) Information processing… Expand

Estimating preselected and postselected ensembles
In analogy with the usual quantum state-estimation problem, we introduce the problem of state estimation for a pre- and postselected ensemble. The problem has fundamental physical significance since,Expand

Asymmetric information capacities of reciprocal pairs of quantum channels
Reciprocal pairs of quantum channels are defined as completely positive transformations which admit a rigid, distance-preserving, yet not completely-positive transformation that allows to reproduceExpand
