我们在脉冲压缩真空中实现了通信波长的非高斯运转。利用钛超导过渡边传感器测量入射光子数，产生了单光子或双光子压缩态。我们观察到所产生的量子态的重构Wigner函数的下降，这提供了明确的证据，非高斯操作已经实现。
We have implemented non-Gaussian operation in pulsed squeezed vacuum at a telecommunications wavelength. A one- or two-photon-subtracted squeezed state was generated using a titanium superconducting transition-edge sensor to resolve the incident photon number. We observed dips in the reconstructed Wigner functions of the generated quantum states, which provides clear evidence that non-Gaussian operation has been realized.
