Quantitative characterization of several entanglement detection criteria
A. Sauer, J. Z. Bernád
Quantitative characterization of different entanglement detection criteria for bipartite systems is presented. We review the implication sequence of these criteria and then numeric…
Optimal two-qubit gates in recurrence protocols of entanglement purification
Francesco Preti, Tommaso Calarco, Juan Mauricio Torres +1
We propose and investigate a method to optimize recurrence entanglement purification protocols. The approach is based on a numerical search in the whole set of SU(4) matrices with…
Estimation of disorders in the rest positions of two membranes in optomechanical systems
Claudio Sanavio, József Zsolt Bernád, André Xuereb
The formalism of quantum estimation theory is applied to estimate the disorders in the positions of two membranes positioned in a driven cavity. We consider the coupled-cavities an…
Range of applicability of the Hu-Paz-Zhang master equation
G. Homa, A. Csordás, M. A. Csirik +1
We investigate a case of the Hu-Paz-Zhang master equation of the Caldeira-Leggett model without Lindblad form obtained in the weak-coupling limit up to the second-order perturbatio…
Fisher-information-based estimation of optomechanical coupling strengths
Claudio Sanavio, József Zsolt Bernád, André Xuereb
The formalism of quantum estimation theory, focusing on the quantum and classical Fisher information, is applied to the estimation of the coupling strength in an optomechanical sys…
Product formulas in the framework of mean ergodic theorems
J. Z. Bernád
An extension of Chernoff's product formula for one-parameter functions taking values in the space of bounded linear operators on a Banach space is given. Essentially, the -th on…
