Universality and optimality of programmable quantum processors
Mario Ziman, Vladimir Buzek
We analyze and compare the optimality of approximate and probabilistic universal programmable quantum processors. We define several characteristics how to quantify the optimality a…
Entanglement, purity and energy: Two qubits vs Two modes
Derek McHugh, Mario Ziman, Vladimir Buzek
We study the relationship between the entanglement, mixedness and energy of two-qubit and two-mode Gaussian quantum states. We parametrize the set of allowed states of these two fu…
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…
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…
