Fermionic one-body entanglement as a thermodynamic resource
Krzysztof Ptaszynski, Massimiliano Esposito
There is ongoing controversy about whether a coherent superposition of the occupied states of two fermionic modes should be regarded entangled or not, that is, whether its intrinsi…
Quantum correlations in dissipative gain-loss systems across exceptional points
Federico Roccati, Archak Purkayastha, G. Massimo Palma +1
We investigate the behavior of correlations dynamics in a dissipative gain-loss system. First, we consider a setup made of two coupled lossy oscillators, with one of them subject t…
A time-dependent regularization of the Redfield equation
Antonio D'Abbruzzo, Vasco Cavina, Vittorio Giovannetti
We introduce a new regularization of the Redfield equation based on a replacement of the Kossakowski matrix with its closest positive semidefinite neighbor. Unlike most of the exis…
Time-Optimal Quantum Driving by Variational Circuit Learning
Tangyou Huang, Yongcheng Ding, Léonce Dupays +4
The simulation of quantum dynamics on a digital quantum computer with parameterized circuits has widespread applications in fundamental and applied physics and chemistry. In this c…
Optimal Control Methods for Quantum Batteries
Francesco Mazzoncini, Vasco Cavina, Gian Marcello Andolina +2
We investigate the optimal charging processes for several models of quantum batteries, finding how to maximize the energy stored in a given battery with a finite-time modulation of…
Quantum Alchemy and Universal Orthogonality Catastrophe in One-Dimensional Anyons
Naim E. Mackel, Jing Yang, Adolfo del Campo
Many-particle quantum systems with intermediate anyonic exchange statistics are supported in one spatial dimension. In this context, the anyon-anyon mapping is recast as a continuo…
Thermodynamic consistency of quantum master equations
Ariane Soret, Vasco Cavina, Massimiliano Esposito
Starting from a microscopic system-baths description, we derive the general conditions for a time-local quantum master equation (QME) to satisfy the first and second law of thermod…
Quantum speed limits on operator flows and correlation functions
Nicoletta Carabba, Niklas Hörnedal, Adolfo del Campo
Quantum speed limits (QSLs) identify fundamental time scales of physical processes by providing lower bounds on the rate of change of a quantum state or the expectation value of an…
Quantum correlations beyond entanglement in a classical-channel model of gravity
Federico Roccati, Benedetto Militello, Emilio Fiordilino +4
A direct quantization of the Newtonian interaction between two masses is known to establish entanglement, which if detected would witness the quantum nature of the gravitational fi…
Noise-assisted and monitoring-enhanced quantum bath tagging
Donato Farina, Vasco Cavina, Marco G. Genoni +1
We analyze the capability of discriminating the statistical nature of a thermal bath by exploiting the interaction with an additional environment. We first shows that, at differenc…
Analyticity constraints bound the decay of the spectral form factor
Pablo Martinez-Azcona, Aurélia Chenu
Quantum chaos cannot develop faster than for systems in thermal equilibrium [Maldacena, Shenker & Stanford, JHEP (2016)]. This `MSS bound' on the Lyapunov exp…
Ultimate Speed Limits to the Growth of Operator Complexity
Niklas Hörnedal, Nicoletta Carabba, Apollonas S. Matsoukas-Roubeas +1
In an isolated system, the time evolution of a given observable in the Heisenberg picture can be efficiently represented in Krylov space. In this representation, an initial operato…
Unitary Evolutions Sourced By Interacting Quantum Memories: Closed Quantum Systems Directing Themselves Using Their State Histories
Alireza Tavanfar, Aliasghar Parvizi, Marco Pezzutto
We propose, formulate and examine novel quantum systems and behavioral phases in which momentary choices of the system's memories interact in order to source the internal interacti…
