Robertson-Schroedinger type formulation of Ozawa's noise-disturbance uncertainty principle
Catarina Bastos, Alex E. Bernardini, Orfeu Bertolami +2
In this work we derive a matrix formulation of a noise-disturbance uncertainty relation, which is akin to the Robertson-Schrödinger uncertainty principle. Our inequality is stronge…
Entanglement due to noncommutativity in the phase-space
Catarina Bastos, Alex E. Bernardini, Orfeu Bertolami +2
The entanglement criterion for continuous variable systems and the conditions under which the uncertainty relations are fulfilled are generalized to the case of a noncommutative (N…
Probing phase-space noncommutativity through quantum beating, missing information and the thermodynamic limit
Alex E. Bernardini, O. Bertolami
In this work we examine the effect of phase-space noncommutativity on some typically quantum properties such as quantum beating, quantum information, and decoherence. To exemplify…
