Quantum metrology via chaos in a driven Bose-Josephson system
Quantum metrology via chaos in a driven Bose-Josephson system
Entanglement preparation and signal accumulation are essential for quantum parameter estimations, which pose significant challenges to both theories and experiments. Here, we propose how to utilize chaotic dynamics in a periodically driven Bose-Josephson system for achieving high-precision measurements beyond the standard quantum limit (SQL). Starting from an initial nonentangled state, …
