Floquet time crystals as quantum sensors of ac fields
Fernando Iemini, Rosario Fazio, Anna Sanpera
Abstract
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.
