Optimal reconstruction of a pure qubit state with local measurements
E. Bagan, M. Baig, A. Monras +1
We analyse the reconstruction of an unknown pure qubit state. We derive the optimal guess that can be inferred from any set of measurements on N identical copies of the system with…

Communicating a direction using spin states
E. Bagan, M. Baig, R. Munoz-Tapia
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…
