Nuclear Numerical Range and Quantum Error Correction Codes for non-unitary noise models
Patryk Lipka-Bartosik, Karol Życzkowski
We introduce a notion of nuclear numerical range defined as the set of expectation values of a given operator among normalized pure states, which belong to the nucleus of an au…
Twin Photon Correlations in Single-Photon Interference
Mayukh Lahiri, Armin Hochrainer, Radek Lapkiewicz +2
We show that it is possible to generate a novel single-photon fringe pattern by using two spatially separated identical bi-photon sources. The fringes are similar to the ones obser…
Inhibiting decoherence of two-level atom in thermal bath by presence of boundaries
Xiaobao Liu, Zehua Tian, Jieci Wang +1
We study, in the paradigm of open quantum systems, the dynamics of quantum coherence of a static polarizable two-level atom which is coupled with a thermal bath of fluctuating elec…
Role of Particle Entanglement in the Violation of Bell Inequalities
T. Wasak, A. Smerzi, J. Chwedenczuk
Entanglement between two separate systems is a necessary resource to violate a Bell inequality in a test of local realism. We demonstrate that to overcome the Bell bound, this corr…
Parameter estimation in the presence of the most general Gaussian dissipative reservoir
Marcin Jarzyna, Marcin Zwierz
We analyze the performance of quantum parameter estimation in the presence of the most general Gaussian dissipative reservoir. We derive lower bounds on the precision of phase esti…
Metric and classical fidelity uncertainty relations for random unitary matrices
Radosław Adamczak
We analyze uncertainty relations on finite dimensional Hilbert spaces expressed in terms of classical fidelity, which are stronger then metric uncertainty relations introduced by F…
