Generation of path-encoded GHZ states in an integrated platform


We present an integrated optical device for the generation of Greenberger-Horne-Zeilinger (GHZ) states of three path-entangled photons. Inspired by the seminal work of Bouwmeester et al. [1] on polarization-entangled GHZ states, we find a corresponding path representation for the photon states of an integrated circuit and identify the optical elements required for the state generation. Besides the noteworthy advantage of employing an integrated system that can be fabricated with proven lithographic techniques, our scheme also improves the generation efficiency by using microring resonators.
