Quantum jumps in driven-dissipative disordered many-body systems
Sparsh Gupta, Hari Kumar Yadalam, Manas Kulkarni, and Camille Aron
Phys. Rev. A 109, L050201 (2024) - Published 6 May, 2024
The authors investigate whether nonequilibrium environments can promote localization rather than destabilize it. By studying the impact of quantum jumps on the localization transition in driven-dissipative systems, the authors reveal pathways to enhance localized regimes using simple yet realistic postselection schemes.
First passage times for continuous quantum measurement currents
Michael J. Kewming, Anthony Kiely, Steve Campbell, and Gabriel T. Landi
Phys. Rev. A 109, L050202 (2024) - Published 20 May, 2024
The authors study First-Passage-Time distributions, and how they can be computed for stochastic measurement currents. They gain insights into signal-to-noise-ratio bounds and false positive reduction strategies, and charge-resolved master equations.
Floquet time crystals as quantum sensors of ac fields
Fernando Iemini, Rosario Fazio, and Anna Sanpera
Phys. Rev. A 109, L050203 (2024) - Published 30 May, 2024
The authors investigate the use of time-crystal phases for metrology, providing a concrete proposal as quantum sensors of AC fields. Their performance shows several useful advantages due to their long-range spatiotemporal ordering, overcoming the shot noise limit along with long interrogation times and robustness.
