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…

Collective vs local measurements in qubit mixed state estimation
E. Bagan, M. Baig, R. Munoz-Tapia +1
We discuss the problem of estimating a general (mixed) qubit state. We give the optimal guess that can be inferred from any given set of measurements. For collective measurements a…

Entanglement assisted alignment of reference frames using a dense covariant coding
E. Bagan, M. Baig, R. Munoz-Tapia
We present a procedure inspired by dense coding, which enables a highly efficient transmission of information of a continuous nature. The procedure requires the sender and the reci…
