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…
Highly non-Gaussian states created via cross-Kerr nonlinearity
Tomas Tyc, Natalia Korolkova
We propose a feasible scheme for generation of strongly non-Gaussian states using the cross-Kerr nonlinearity. The resultant states are highly non-classical states of electromagnet…
Gaussian quantum marginal problem
J. Eisert, T. Tyc, T. Rudolph +1
The quantum marginal problem asks what local spectra are consistent with a given spectrum of a joint state of a composite quantum system. This setting, also referred to as the ques…
Operational formulation of homodyne detection
Tomas Tyc, Barry C. Sanders
We obtain the standard quadrature-phase positive operator-valued measure (POVM) for homodyne detection directly and rigorously from the POVM for photon counting without directly em…
