Bures geodesics and quantum metrology
Dominique Spehner
We study the geodesics on the manifold of mixed quantum states for the Bures metric. It is shown that these geodesics correspond to physical non-Markovian evolutions of the system…
Persistent currents in Bose-Bose mixtures after an interspecies interaction quench
Dominique Spehner, Luis Morales-Molina, Sebastián Reyes
We study the persistent currents and interspecies entanglement generation in a Bose-Bose mixture formed by two atomic gases (hereafter labelled by the letters A and B) trapped in a…
Geometric measures of quantum correlations with Bures and Hellinger distances
D. Spehner, F. Illuminati, M. Orszag +1
This article contains a survey of the geometric approach to quantum correlations. We focus mainly on the geometric measures of quantum correlations based on the Bures and quantum H…
Geometric measures of quantum correlations: characterization, quantification, and comparison by distances and operations
Wojciech Roga, Dominique Spehner, Fabrizio Illuminati
We investigate and compare three distinguished geometric measures of bipartite quantum correlations that have been recently introduced in the literature: the geometric discord, the…
Quantum correlations and distinguishability of quantum states
Dominique Spehner
A survey of various concepts in quantum information is given, with a main emphasis on the distinguishability of quantum states and quantum correlations. Covered topics include gene…
Harnessing synthetic gauge fields for maximally entangled state generation
Sebastian A. Reyes, Luis Morales-Molina, Miguel Orszag +1
We study the generation of entanglement between two species of neutral cold atoms living on an optical ring lattice, where each group of particles can be described by a -dimensi…
