Ghost unitaries for loss-resilient photonic resource-state generation
Kevin J. Randles, Manuel H. Muñoz-Arias, Kevin Thompson
Entangled few-photon states, such as Bell and Greenberger-Horne-Zeilinger (GHZ) states, are central resources for discrete-variable photonic quantum information processing. In many…
