Abstract

We propose a measurement protocol to generate path-entangled \ensuremath|N,0⟩+\ensuremath|0,N⟩ states conditionally from two pulsed type II optical parametric oscillators. We calculate the fidelity of the produced states and the success probability of the protocol. The trigger detectors are assumed to have finite dead time, and for short pulse trigger fields they are modeled as on-off detectors with finite efficiency. Continuous-wave operation of the parametric oscillators is also considered.
