Unambiguous identification of coherent states II: Multiple resources
Michal Sedlak, Mario Ziman, Vladimir Buzek +1
We consider unambiguous identification of coherent states of electromagnetic field. In particular, we study possible generalizations of an optical setup proposed in M. Sedlák {\it…
Unambiguous comparison of unitary channels
Michal Sedlak, Mario Ziman
We address the problem of unambiguous comparison of a pair of unknown qudit unitary channels. Using the framework of process positive operator valued measures (PPOVM) we characteri…
Unambiguous comparison of ensembles of quantum states
Michal Sedlak, Mario Ziman, Vladimir Buzek +1
We present a solution of the problem of the optimal unambiguous comparison of two ensembles of unknown quantum states (psi_1)^k and (psi_2)^l. We consider two cases: 1) The two unk…
Unambiguous coherent state identification: Searching a quantum database
Michal Sedlak, Mario Ziman, Ondrej Pribyla +2
We consider an unambiguous identification of an unknown coherent state with one of two unknown coherent reference states. Specifically, we consider two modes of an electromagnetic…
