The realization of fault-tolerant optical quantum computation requires non-Gaussian states. Non-Gaussian states are generated probabilistically by heralding method, and the non-classicality of the generated states and the generation rate are important indicators. Superconducting nanostrip photon number resolving detectors (SNSPDs) are promising for high generation rates of advanced quantum states due to their small timing jitter of about 10 ps and recently demonstrated photon number discrimination capability. In this study, we report the first successful generation of non-Gaussian states using SNSPDs.
