Position- and Momentum-Space Quantum Information Measures of the Double-Morse Oscillator
Firoz Chogle, Ernesto Damiani, Berihu Teklu
We investigate the quantum-information properties of a particle confined by the double Morse potential in position and momentum spaces. The quasi-exact solvability of the model giv…
Efficient simulation of noisy entanglement generation
Lorenzo Brevi, Federico Grasselli, Alessandro Caraceni +3
End-to-end entanglement distribution is a key capability of upcoming quantum networks, enabling applications like distributed quantum computing, quantum sensor networks, and secure…
Enhanced quantum metrology by criticality-assisted noncommutative preparation
Ningxin Kong, Matteo G. A. Paris, Qiongyi He
Quantum criticality is a resource for quantum-enhanced metrology, but existing schemes face intrinsic limitations. These arise because using criticality directly in the encoding dy…
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 communications in continuous variable systems
Michele N. Notarnicola
Nowadays, quantum communications provide a vast field of research in rapid expansion, with a huge potential impact on the future developments of quantum technologies. In particular…
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…
Shake before use: universal enhancement of quantum thermometry by unitary driving
Emanuele Tumbiolo, Lorenzo Maccone, Chiara Macchiavello +2
Quantum thermometry aims at determining temperature with ultimate precision in the quantum regime. Standard equilibrium approaches, limited by the Quantum Fisher Information given…
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…
Statistical phase-space complexity of continuous-variable quantum channels
Siting Tang, Francesco Albarelli, Yue Zhang +2
The statistical complexity of continuous-variable quantum states can be characterized with a quantifier defined in terms of information-theoretic quantities derived from the Husimi…
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…

We investigate the optimization of graph topologies for quantum sensing networks designed to estimate weak magnetic fields. The sensors are modeled as spin systems governed by a tr…
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…
