Quantum Fisher information and imperfect detection in a monitored fermion chain
Giovanni Di Fresco, Davide Valenti, Angelo Carollo
We study the metrological properties of a continuously monitored Kitaev chain in the presence of imperfect detection. The system is conditioned on a no-click record, while each emi…

Quantum optics with giant atoms in a structured photonic bath
L. Leonforte, X. Sun, D. Valenti +4
We present a general framework to tackle quantum optics problems with giant atoms, i.e. quantum emitters each coupled {\it non-locally} to a structured photonic bath (typically a l…
