Fock-state preparation from thermal cavity fields by measurements on resonant atoms
G. Harel, Gershon Kurizki · Physical Review A · 1996
We show that by combining nonselective and conditional measurements on a sequence of excited two-level atoms traversing a resonant cavity, one can construct a practical strategy for compressing an arbitrary photon-number distribution (thermal distributions included) into a desired Fock state with high probability of success and low number of measurements. \textcopyright{} 1996 The American Physical Society.
