Effective dynamics from minimising dissipation
Antonio F. Rotundo, Paolo Perinotti, Alessandro Bisio
It is known that the same physical system can be described by different effective theories depending on the scale at which it is observed. In this work, we formulate a prescription…
Reliable quantum advantage in quantum battery charging
Davide Rinaldi, Radim Filip, Dario Gerace +1
Quantum batteries represent one of the most promising applications of quantum thermodynamics, whose goal is not only to store energy inside small quantum systems but also to potent…
Frequency-bin entanglement-based quantum key distribution
Noemi Tagliavacche, Massimo Borghi, Giulia Guarda +5
Entanglement is an essential ingredient in many quantum communication protocols. In particular, entanglement can be exploited in quantum key distribution (QKD) to generate two corr…
Quantum Key Distribution with Basis-Dependent Detection Probability
Federico Grasselli, Giovanni Chesi, Nathan Walk +7
Quantum Key Distribution (QKD) is a promising technology for secure communication. Nevertheless, QKD is still treated with caution in certain contexts due to potential gaps between…
Quantum-enhanced dark matter detection with in-cavity control: mitigating the Rayleigh curse
Haowei Shi, Anthony J. Brady, Wojciech Górecki +3
The nature of dark matter is a fundamental puzzle in modern physics. A major approach of searching for dark matter relies on detecting feeble noise in microwave cavities. However,…

Interplay between time and energy in bosonic noisy quantum metrology
Wojciech Górecki, Francesco Albarelli, Simone Felicetti +2
Quantum entanglement and coherence often allow for protocols that outperform classical ones in estimating a system's parameter. When using infinite-dimensional probes (such as a bo…
Stability of emergent time periodicity in a few-body interacting system
Steve Campbell, Jens Eisert, Giacomo Guarnieri
We examine the onset and resilience of emergent time periodicity in a few-body all-to-all interacting Lipkin-Meshkov-Glick model, where one of the constituents is locally in contac…
