Relations between Markovian and non-Markovian correlations in multitime quantum processes
Guilherme Zambon, Diogo O. Soares-Pinto
In the dynamics of open quantum systems, information may propagate in time through either the system or the environment, giving rise to Markovian and non-Markovian temporal correla…
Quantum Speed Limits Based on Schatten Norms: Universality and Tightness
Alberto J. B. Rosal, Diogo O. Soares-Pinto, Diego Paiva Pires
We discuss quantum speed limits (QSLs) for finite-dimensional quantum systems undergoing general physical processes. These QSLs were obtained using Schatten -norms, firstly expl…
Variational-quantum-eigensolver-inspired optimization for spin-chain work extraction
Ivan Medina, Alexandre Drinko, Guilherme I. Correr +2
The energy extraction from quantum sources is a key task to develop new quantum devices such as quantum batteries (QB). In this context, one of the main figures of merit is the erg…
Detecting quantum phase transitions in a frustrated spin chain via transfer learning of a quantum classifier algorithm
André J. Ferreira-Martins, Leandro Silva, Alberto Palhares +4
The classification of phases and the detection of phase transitions are central and challenging tasks in diverse fields. Within physics, it relies on the identification of order pa…
Experimental Investigation of Geometric Quantum Speed Limits in an Open Quantum System
Diego Paiva Pires, Eduardo R. deAzevedo, Diogo O. Soares-Pinto +2
We studied geometric quantum speed limits (QSL) of a qubit subject to decoherence in an ensemble of chloroform molecules in a Nuclear Magnetic Resonance experiment. The QSL is a fu…
Quantum walks with spatiotemporal fractal disorder
Marcelo A. Pires, Caio B. Naves, Diogo O. Soares-Pinto +1
We investigate the transport and entanglement properties exhibited by quantum walks with coin operators concatenated in a space-time fractal structure. Inspired by recent developme…
