Abstract

We have implemented the non-Gaussian operation on the pulsed squeezed vacuum at telecommunication wavelengths. The non-Gaussian operation based on photon subtraction was carried out using a Titanium-based superconducting transition-edge-sensor that can resolve the photon number. We observed a dip in reconstructed Wigner functions of generated quantum states, which is the clear evidence that a non-Gaussian operation was realized.
