Deterministic generation of nonclassical photons by producing a dilute gas of exciton-polaritons in a solid-state microcavity that includes a periodic array of potential well traps. A photon-exciton frequency detuning is modulated in the microcavity to produce a polaritonic quantum phase transition from a superfluid state to a Mott-insulator state. The nonclassical photons are then generated simultaneously by radiative decay of exciton-polaritons in the microcavity.

Alternatively, the generated nonclassical photons may be polarization-entangled photon pairs, in which case the dilute gas of exciton-polaritons is produced such that on average there are two polaritons per potential well trap.
