Abstract

Photonic quantum computation via bulk optical nonlinearities presents challenges, due to the weakness of nonlinearity and the difficulties in doing without feed-forward control. Here, the authors propose an all-unitary approach that is based on a triply-resonant cavity with a time-dependent drive.
