Exponentially accelerated relaxation and quantum Mpemba effect in open quantum systems
Emerson Lima Caldas, Diego Paiva Pires
We investigate the quantum Mpemba effect in the relaxation of open quantum systems whose effective dynamics is described by Davies maps. We introduce a class of unitary transformat…
Quantum speed limits based on Jensen-Shannon and Jeffreys divergences for general physical processes
Jucelino Ferreira de Sousa, Diego Paiva Pires
We discuss quantum speed limits (QSLs) for finite-dimensional quantum systems undergoing general physical processes. These QSLs were obtained using two families of entropic measure…
Generalized Entropic Quantum Speed Limits
Jucelino Ferreira de Sousa, Diego Paiva Pires
We present a class of generalized entropic quantum speed limits based on --Rényi relative entropy, a real-valued, contractive, two-parameter family of distinguishability meas…
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…
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…
Fidelity-based distance bounds for -qubit approximate quantum error correction
Guilherme Fiusa, Diogo O. Soares-Pinto, Diego Paiva Pires
The Eastin-Knill theorem is a central result of quantum error correction theory and states that a quantum code cannot correct errors exactly, possess continuous symmetries, and imp…
