Bounding generalized relative entropies: Nonasymptotic quantum speed limits
Diego Paiva Pires, Kavan Modi, Lucas Chibebe Céleri
Information theory has become an increasingly important research field to better understand quantum mechanics. Noteworthy, it covers both foundational and applied perspectives, als…
Quantum coherence and speed limit in the mean-field Dicke model of superradiance
D. Z. Rossatto, D. P. Pires, F. M. de Paula +1
Dicke superrandiance is a cooperative phenomenon which arises from the collective coupling of an ensemble of atoms to the electromagnetic radiation. Here we discuss the quantifying…
Relating relative Rényi entropies and Wigner-Yanase-Dyson skew information to generalized multiple quantum coherences
Diego Paiva Pires, Augusto Smerzi, Tommaso Macrì
Quantum coherence is a crucial resource for quantum information processing. By employing the language of coherence orders largely applied in NMR systems, quantum coherence has been…
Spin-orbit coupling in wurtzite quantum wells
J. Y. Fu, P. H. Penteado, D. R. Candido +4
Effective spin-orbit (SO) Hamiltonians for conduction electrons in wurtzite heterostructures are lacking in the literature, in contrast to zincblende structures. Here we address th…
