Quantum walks with random phase shifts
Jozef Kosik, Vladimir Buzek, Mark Hillery
We investigate quantum walks in multiple dimensions with different quantum coins. We augment the model by assuming that at each step the amplitudes of the coin state are multiplied…
Entanglement conditions for two-mode states: Applications
Mark Hillery, M. Suhail Zubairy
We examine the implications of several recently derived conditions [Hillery and Zubairy, Phys. Rev. Lett. 96, 050503 (2006)] for determining when a two-mode state is entangled. We…
Programmable quantum state discriminators with simple programs
Janos A. Bergou, Vladimir Buzek, Edgar Feldman +2
We describe a class of programmable devices that can discriminate between two quantum states. We consider two cases. In the first, both states are unknown. One copy of each of the…
Optimal unambiguous discrimination of two subspaces as a case in mixed state discrimination
Janos A. Bergou, Edgar Feldman, Mark Hillery
We show how to optimally unambiguously discriminate between two subspaces of a Hilbert space. In particular we suppose that we are given a quantum system in either the state ψ_{1},…
