Fluctuation theorems with retrodiction rather than reverse processes
Irreversibility is usually captured by a comparison between the process that happens and a
corresponding “reverse process.” In the last decades, this comparison has been extensively …

Noisy atomic magnetometry in real time
Continuously monitored atomic spin-ensembles allow, in principle, for real-time sensing of
external magnetic fields beyond classical limits. Within the linear-Gaussian regime, thanks to …

Quantum retrodiction: Foundations and controversies
Prediction is the making of statements, usually probabilistic, about future events based on
current information. Retrodiction is the making of statements about past events based on …

Prediction-retrodiction measurements for teleportation and conditional state transfer
Regular measurements allow predicting the future and retrodicting the past of quantum
systems. Time-nonlocal measurements can leave the future and the past uncertain, yet …
