Generation of Schrödinger's cat state in an optical double sideband mode

An optical Schrodigner's cat state is generated in 500.6 MHz double sideband mode of continuous wave light. We used phase modulation to selectively subtract a photon from sideband. The reconstructed Wigner function exhibits a significant negativity of -0.088 ± 0.001 without any correction.
