Thermalization in Spatially Extended Open Quantum Systems: Local versus Global Markovian Evolution
Jorge Tabanera-Bravo, Massimiliano Esposito, Felipe Barra +1
We investigate the dynamics of a qubit chain locally coupled to a thermal reservoir, modeled through repeated collisions with particles drawn from a heat bath. Under suitable condi…
Purely quantum memory in closed systems observed via imperfect measurements
Jorge Tabanera-Bravo, Aljaž Godec
The detection and quantification of non-Markovianity, a.k.a. memory, in quantum systems is a central problem in the theory of open quantum systems. There memory is as a result of t…
Extra cost of erasure due to quantum lifetime broadening
Joe Dunlop, Federico Cerisola, Juliette Monsel +6
The energy cost of erasing a bit of information was fundamentally lower bounded by Landauer, in terms of the temperature of its environment: . However,…
Thermodynamically Optimal Protocols for Dual-Purpose Qubit Operations
Joe Dunlop, Federico Cerisola, Jorge Tabanera-Bravo +1
Information processing, quantum or classical, relies on channels transforming multiple input states to different corresponding outputs. Previous research has established bounds on…
