Non-Gaussian quantum state generation by multi-photon subtraction at the telecommunication wavelength

Non-Gaussian quantum state generation by multi-photon subtraction at the telecommunication wavelength In the field of continuous-variable quantum information processing, non-Gaussian states with negative values of the Wigner function are crucial for the development of a fault-tolerant universal quantum computer. While several non-Gaussian states have been generated experimentally, none have been created using ultrashort optical wave packets, which are necessary for high-speed quantum computatio...
