QuantGraph: A Receding-Horizon Quantum Graph Solver
Pranav Vaidhyanathan, Aristotelis Papatheodorou, David R. M. Arvidsson-Shukur +3
Dynamic programming is a cornerstone of graph-based optimization. While effective, it scales unfavorably with problem size. In this work, we present QuantGraph, a two-stage quantum…
Thermodynamic universality across dissipative quantum phase transitions
Laetitia P. Bettmann, Artur M. Lacerda, Mark T. Mitchison +1
We study finite-time driving across second-order dissipative quantum phase transitions described by Lindblad dynamics. We show that the nonadiabatic entropy production, which quant…
Current fluctuations in nonequilibrium open quantum systems beyond weak coupling: a reaction coordinate approach
Khalak Mahadeviya, Saulo V. Moreira, Sheikh Parvez Mandal +3
We investigate current fluctuations in open quantum systems beyond the weak-coupling and Markovian regimes, focusing on a coherently driven qubit strongly coupled to a structured b…
Correlated decoherence and thermometry with mobile impurities in a 1D Fermi gas
Sindre Brattegard, Thomás Fogarty, Thomas Busch +1
We theoretically investigate the correlated decoherence dynamics of two mobile impurities trapped within a gas of ultracold fermionic atoms. We use a mean-field approximation to se…
Quantum detectors as autonomous machines: assessing the nonequilibrium thermodynamics of information acquisition
Emanuel Schwarzhans, Tony J. G. Apollaro, Ilia Khomchenko +3
We formulate a minimal model of a quantum particle detector as an autonomous quantum thermal machine. Our goal is to establish how entropy production, which is needed to maintain t…
Current-based metrology with two-terminal mesoscopic conductors
Shishir Khandelwal, Gabriel T. Landi, Géraldine Haack +1
The traditional approach to quantum parameter estimation focuses on the quantum state, deriving fundamental bounds on precision through the quantum Fisher information. In most expe…
Steady-state heat engines driven by finite reservoirs
Iago N. Mamede, Saulo V. Moreira, Mark T. Mitchison +1
We provide a consistent thermodynamic analysis of stochastic thermal engines driven by finite-size reservoirs, which are in turn coupled to infinite-size reservoirs. We consider a…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Heat operator approach to quantum stochastic thermodynamics in the strong-coupling regime
Sheikh Parvez Mandal, Mahasweta Pandit, Khalak Mahadeviya +2
Heat exchanged between an open quantum system and its environment exhibits fluctuations that carry crucial signatures of the underlying dynamics. Within the well-established two-po…
MetaSym: A Symplectic Meta-learning Framework for Physical Intelligence
Pranav Vaidhyanathan, Aristotelis Papatheodorou, Mark T. Mitchison +2
Scalable and generalizable physics-aware deep learning has long been considered a significant challenge with various applications across diverse domains ranging from robotics to mo…
Diagnosing chaos with projected ensembles of process tensors
Peter O'Donovan, Neil Dowling, Kavan Modi +1
The process tensor provides a general representation of a quantum system evolving under repeated interventions and is fundamental for numerical simulations of local many-body dynam…
Entropic costs of extracting classical ticks from a quantum clock
Vivek Wadhia, Florian Meier, Federico Fedele +12
We experimentally realize a quantum clock by using a charge sensor to count charges tunneling through a double quantum dot (DQD). Individual tunneling events are used as the clock'…
