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…
Entanglement transformation with no classical communication
Bing He, János A. Bergou
We present an optimal scheme to realize the transformations between single copies of two bipartite entangled states without classical communication between the sharing parties. The…
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…
Universal discriminator for completely unknown optical qubits
Bing He, Janos A. Bergou, Yuhang Ren
We propose an experimental setup that is capable of unambiguously discriminating any pair of linearly independent single photon polarization qubits, about which we don't have any k…
Quantum Non-Demolition Test of Bipartite Complementarity
F. de Melo, S. P. Walborn, János A. Bergou +1
We present a quantum circuit that implements a non-demolition measurement of complementary single- and bi-partite properties of a two-qubit system: entanglement and single-partite…
