Battery charging in collision models with Bayesian risk strategies
Gabriel T. Landi
We construct a collision model where measurements in the system, together with a Bayesian decision rule, are used to classify the incoming ancillas as having either high or low erg…
Quantum quench thermodynamics at high temperatures
Adalberto D. Varizi, Raphael C. Drumond, Gabriel T. Landi
The entropy produced when a system undergoes an infinitesimal quench is directly linked to the work parameter susceptibility, making it sensitive to the existence of a quantum crit…
Enhancing entanglement and total correlations dynamics via local unitaries
Joab Morais Varela, Ranieri Nery, George Moreno +3
The interaction with the environment is one of the main obstacles to be circumvented in practical implementations of quantum information tasks. The use of local unitaries, while no…
Hyperaccurate thermoelectric currents
André, M. Timpanaro, Giacomo Guarnieri +1
Thermodynamic currents can fluctuate significantly at the nanoscale. But some currents fluctuate less than others. Hyperaccurate currents are those which fluctuate the least, in th…
Two-point measurement of entropy production from the outcomes of a single experiment with correlated photon pairs
Gabriel H. Aguilar, Thaís L. Silva, Thiago E. Guimarães +3
Fluctuation theorems are one of the pillars of non-equilibrium thermodynamics. Broadly speaking, they concern the statistical distribution of quantities such as heat, work or entro…
Waiting-times statistics in boundary driven free fermion chains
Gabriel T. Landi
We study the waiting-time distributions (WTDs) of quantum chains coupled to two Lindblad baths at each end. Our focus is on free fermion chains, where we derive closed-form express…
Machine classification for probe based quantum thermometry
Fabrício S. Luiz, A. de Oliveira Junior, Felipe F. Fanchini +1
We consider probe-based quantum thermometry and show that machine classification can provide model-independent estimation with quantifiable error assessment. Our approach is based…
Bayesian estimation for collisional thermometry
Gabriel O. Alves, Gabriel T. Landi
Quantum thermometry exploits the high level of control in coherent devices to offer enhanced precision for temperature estimation. This highlights the need for constructing concret…
Dephasing enhanced transport in boundary-driven quasiperiodic chains
Artur M. Lacerda, John Goold, Gabriel T. Landi
We study dephasing-enhanced transport in boundary-driven quasi-periodic systems. Specifically we consider dephasing modelled by current preserving Lindblad dissipators acting on th…
Quantum thermoelectric transmission functions with minimal current fluctuations
Andre M. Timpanaro, Giacomo Guarnieri, Gabriel T. Landi
Thermodynamic uncertainty relations (TURs) represent a benchmark result in nonequilibrium physics that allows to place fundamental lower bounds on the noise-to-signal ratio (precis…
Informational steady-states and conditional entropy production in continuously monitored systems: the case of Gaussian systems
Alessio Belenchia, Mauro Paternostro, Gabriel T. Landi
The act of measuring a system has profound consequences of dynamical and thermodynamic nature. In particular, the degree of irreversibility ensuing from a non-equilibrium process i…
Correlations break homogenization
Naim Elias Comar, Gabriel T. Landi
The standard collisional model paradigm consists of a system that interacts sequentially with identically prepared ancillas. After infinitely many collisions, and under appropriate…
Multipartite quantum correlations in a two-mode Dicke model
Rodolfo Soldati, Mark T. Mitchison, Gabriel T. Landi
We analyze multipartite correlations in a generalized Dicke model involving two optical modes interacting with an ensemble of two-level atoms. In particular, we examine correlation…
Extracting Bayesian networks from multiple copies of a quantum system
Kaonan Micadei, Gabriel T. Landi, Eric Lutz
Despite their theoretical importance, dynamic Bayesian networks associated with quantum processes are currently not accessible experimentally. We here describe a general scheme to…
Non-equilibrium boundary driven quantum systems: models, methods and properties
Gabriel T. Landi, Dario Poletti, Gernot Schaller
Recent years have seen tremendous progress in the theoretical understanding of quantum systems driven dissipatively by coupling them to different baths at their edges. This was pos…
Quantum mean-square predictors and thermodynamics
Marcelo Janovitch, Gabriel T. Landi
Thermodynamic quantities, such as heat and work, are not functions of state, but rather of the process undergone by a physical system. Assessing them can therefore be difficult, si…
Informational steady-states and conditional entropy production in continuously monitored systems
Gabriel T. Landi, Mauro Paternostro, Alessio Belenchia
We put forth a unifying formalism for the description of the thermodynamics of continuously monitored systems, where measurements are only performed on the environment connected to…
Contributions from populations and coherences in non-equilibrium entropy production
Adalberto D. Varizi, Mariana A. Cipolla, Martí Perarnau-Llobet +2
The entropy produced when a quantum system is driven away from equilibrium can be decomposed in two parts, one related with populations and the other with quantum coherences. The l…
