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…
Fundamental String and D1-brane in I-brane Background
J. Kluson
This paper is devoted to the study of dynamics of fundamental string and D1-brane in I-brane background. We consider configurations where string and D1-brane uniformly wrap transve…
Odd Scalar Curvature in Anti-Poisson Geometry
Igor A. Batalin, Klaus Bering
Recent works have revealed that the recipe for field-antifield quantization of Lagrangian gauge theories can be considerably relaxed when it comes to choosing a path integral measu…
Discrimination of quantum observables using limited resources
Mario Ziman, Teiko Heinosaari
We address the problem of unambiguous discrimination and identification among quantum observables. We set a general framework and investigate in details the case of qubit observabl…
Obstruction theory on 8-manifolds
Martin Cadek, Michael Crabb, Jiri Vanzura
This note gives a uniform, self-contained, and fairly direct approach to a variety of obstruction-theoretic problems on 8-manifolds. We give necessary and sufficient cohomological…
A hydrodynamic scheme for two-component winds from hot stars
V. Votruba, A. Feldmeier, J. Kubát +1
We have developed a time-dependent two-component hydrodynamics code to simulate radiatively-driven stellar winds from hot stars. We use a time-explicit van Leer scheme to solve the…
