Stochastic Quantum Information Geometry and Speed Limits at the Trajectory Level
Pedro B. Melo, Pedro V. Paraguassú, SÃlvio M. Duarte Queirós +3
In quantum metrology, precision is typically characterized by an ensemble-averaged quantity, the quantum Fisher information (QFI), which averages over the fluctuations of individua…
Entangled photons from quantum-dot-cavity systems under non-Markovian decoherence by pulsed excitation
Katy Snow, Mauro Paternostro
Cascaded emission from the biexciton state of a quantum dot results in polarization entangled photon pairs. Cavity-enhancement of the direct two-photon emission channel bypasses th…
Improving device-independent quantum key distribution protocols through multiple routed Bell tests
Sujan Vijayaraj, Mauro Paternostro
Device-independent quantum key distribution (DI-QKD) offers security with the smallest possible set of assumptions about the experimental setup. The challenge posed by its implemen…
Detection of noise correlations in two qubit systems by Machine Learning
Dario Fasone, Shreyasi Mukherjee, Dario Penna +5
We introduce and validate a machine-learning assisted quantum sensing protocol to classify spatial and temporal correlations of classical noise affecting two ultrastrongly coupled…
Efficient classical training of model-free quantum photonic reservoir
Rosario Di Bartolo, Valeria Cimini, Giorgio Minati +10
Model-independent estimation of the properties of quantum states is a central challenge in quantum technologies, as experimental imperfections, drifts, and imprecise models of the…
Robustness of the quantum Mpemba effect against state-preparation errors
Matthew Mackinnon, Mauro Paternostro
The quantum Mpemba effect (QME) is a phenomenon observed in many-body systems where initial systems configurations farther from equilibrium can be observed to equilibrate faster th…
