Abstract:We propose a direct interferometric test of the Non-Linear Phase Shift Gate (NLPSG), an essential piece of a Knill Laflamme Milburn Contolled-NOT (KLM CNOT) gate. We develop our analysis for the both the case of the original, bulk optical KLM NLPSG and for the scalable integrated nano-photonic NLPSG based on Micro-Ring Resonators (MRRs) that we have proposed very recently. Specifically, we consider the interference between the target photon mode of the NLPSG along one arm of a Mach Zehnder Interferometer (MZI)… Show more
