On generalized entropies and information-theoretic Bell inequalities under decoherence
Alexey E. Rastegin
We consider information-theoretic inequalities of the Bell type in the presence of decoherence. It is natural that too strong coupling with the environment can prevent an observati…
On uncertainty relations and entanglement detection with mutually unbiased measurements
Alexey E. Rastegin
We formulate some properties of a set of several mutually unbiased measurements. These properties are used for deriving entropic uncertainty relations. Applications of mutually unb…
Rényi and Tsallis formulations of noise-disturbance trade-off relations
Alexey E. Rastegin
We address an information-theoretic approach to noise and disturbance in quantum measurements. Properties of corresponding probability distributions are characterized by means of b…
Formulation of Leggett-Garg inequalities in terms of -entropies
Alexey E. Rastegin
As is well known, the macroscopic realism and the noninvasive measurability together lead to Leggett-Garg inequalities violated by quantum mechanics. We consider tests of the Legge…
Fine-grained uncertainty relations for several quantum measurements
Alexey E. Rastegin
We study fine-grained uncertainty relations for several quantum measurements in a finite-dimensional Hilbert space. The proposed approach is based on exact calculation or estimatio…
