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…
Arrival time in quantum field theory
Zhi-Yong Wang, Cai-Dong Xiong, Bing He
Via the proper-time eigenstates (event states) instead of the proper-mass eigenstates (particle states), free-motion time-of-arrival theory for massive spin-1/2 particles is develo…
Application of quantum algorithms to the study of permutations and group automorphisms
Marianna Bonanome, Mark Hillery, Vladimir Buzek
We discuss three applications of efficient quantum algorithms to determining properties of permutations and group automorphisms. The first uses the Bernstein-Vazirani algorithm to…
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…
