Non-Markovianity in the Adapted Caldeira-Leggett model
Luciano Manara, Andrea Smirne, Bassano Vacchini
In this work, we investigate the non-Markovian features of the Adapted Caldeira-Leggett model, a computationally efficient framework recently proposed to capture the essential phys…
Quantum jump trajectories, hybrid systems, non-Hermitian evolutions, quantum/classical walks
Alberto Barchielli
Quantum stochastic master equations of jump type are formulated in a general way and connections with quantum/classical hybrid systems and quantum filtering theory are discussed. B…
Security of Binary-Modulated Optical Key Distribution Against Quantum-Enhanced Coherent Eavesdropping
Karol Łukanowski, Michał Wójcik, Stefano Olivares +2
Optical key distribution (OKD) protects the physical layer of communication links by taking advantage of the inherent noise present in the photodetection process. It allows for eff…
Temporal nonclassicality in continuous-time quantum walks
Paolo Luppi, Claudia Benedetti, Andrea Smirne
We investigate the genuinely quantum features of continuous-time quantum walks by combining a single-time and a multi-time quantifier of nonclassicality. On the one hand, we consid…
Boosting Work Extraction in Quantum Batteries via Continuous Environment Monitoring
Gabriele Cenedese, Giuliano Benenti, Dario Ferraro +1
During the charging process, interactions between a quantum battery and its charger generally generate quantum correlations, which may reduce the amount of work extractable from th…
Synchronization effects in a periodically driven two-level system
Federico Settimo, Bassano Vacchini
We study phase-synchronization in a driven two-level system coupled to a non-Markovian bosonic reservoir. The dynamics is described by treating the system-bath coupling and the coh…
Stochastic unravelings for Heisenberg picture and trace-nonpreserving dynamics
Federico Settimo, Kimmo Luoma, Dariusz Chruściński +3
Stochastic unravelings allow to efficiently simulate open system dynamics, yet their application has traditionally been restricted to master equations that preserve both Hermiticit…
Quantum advantage bounds for a multipartite Gaussian battery
F. Cavaliere, D. Ferraro, M. Carrega +2
We demonstrate the possibility of a genuine quantum advantage in the efficiency of quantum batteries by analyzing a model that enables a consistent comparison between quantum and c…
Local energy assignment for two interacting quantum thermal reservoirs
Alessandra Colla, Bassano Vacchini, Andrea Smirne
Understanding how to assign internal energy, heat, and work in quantum systems beyond weak coupling remains a central problem in quantum thermodynamics, particularly as the differe…
Control of memory effects in a spin-boson system by periodic driving
Pietro Follia, Bassano Vacchini, Heinz-Peter Breuer
We study the emergence of quantum memory effects in a spin-boson system at finite temperature driven by an external time-periodic force. Quantifying memory effects by the trace-dis…
Quantum contextuality from measurement invasiveness
Andrea Navoni, Marco G. Genoni, Andrea Smirne
Contextuality is a defining feature that separates the quantum from the classical descriptions of physical systems. Within the marginal-scenario framework, noncontextual models are…
Channel capacity of small modular quantum networks in the ultrastrongly coupled regime
Salvatore Alex Cordovana, Luigi Giannelli, Nicola Macrì +3
We investigate state-transfer in modular quantum computer architectures exploiting the ultrastrong coupling regime of interaction between quantum processing units and ICs. We show…
Optimal quantum transport on a ring via locally monitored chiral quantum walks
Sara Finocchiaro, Giovanni O. Luilli, Giuliano Benenti +2
In purely coherent transport on finite networks, destructive interference can significantly suppress transfer probabilities, which can only reach high values through careful fine-t…
Local and global approaches to the thermodynamics of pure decoherence processes in open quantum systems
Irene Ada Picatoste, Alessandra Colla, Heinz-Peter Breuer
We study the nonequilibrium thermodynamics of pure decoherence processes in open quantum systems coupled to a thermal reservoir. We review various definitions of central quantities…
Higher-Order Adiabatic Elimination in Atom-Cavity Systems and Its Impact on Spin-Squeezing Generation
Stefano Giaccari, Giulia Dellea, Marco G. Genoni +1
Spin-squeezed states are metrologically useful quantum states where entanglement allows for enhanced sensing with respect to the standard quantum limit. Key challenges include the…
Hybrid discrimination strategy in quantum communication based on photon-number-resolving detectors and mesoscopic twin-beam states
Luca Razzoli, Alex Pozzoli, Alessia Allevi
State discrimination is a key challenge in the implementation of quantum communication protocols. Most optical communication protocols rely on either coherent states of light or fr…
Divisibility of dynamical maps: Schrödinger vs. Heisenberg picture
Federico Settimo, Andrea Smirne, Kimmo Luoma +3
Divisibility of dynamical maps is a central notion in the study of quantum non-Markovianity, providing a natural framework to characterize memory effects via time-local master equa…

Alessandra Colla, Heinz-Peter Breuer, Giulio Gasbarri
We develop a recursive perturbative expansion for the time-convolutionless (TCL) generator of an open quantum system in a generalized Lindblad form. This formulation provides a sys…

Postponing the choice: advantage of deferred measurements in quantum information processing
C. Carmeli, T. Heinosaari, A. Toigo
Simultaneously implementing two arbitrary quantum measurements on the same system is impossible. The consequence of this limitation is that selecting one measurement actively exclu…
