Critical Quantum Metrology beyond Adiabaticity in Collectively Pumped Superradiance
Yoav Shimshi · Ephraim Shahmoon
Abstract
Author(s): Yoav Shimshi and Ephraim Shahmoon<br/><p>Critical metrology relies on the high sensitivity of systems to parameter changes near a phase transition to extract information with high precision. Such methods usually require working under adiabatic conditions, which implies long preparation times due to critical slowing down. Here instead we de…</p><br/>[Phys. Rev.
