Deterministic Dicke-state preparation with continuous measurement and control
John K. Stockton, Ramon van Handel, Hideo Mabuchi · Physical Review A · 2004
We characterize the long-time projective behavior of the stochastic master equation describing a continuous, collective spin measurement of an atomic ensemble both analytically and numerically. By adding state-based feedback, we show that it is possible to prepare highly entangled Dicke states deterministically.
