The screen shot of oscilloscope displaying 10000 overlaid events for real-time quadrature measurements for each quadrature phase of the cat states. The characteristic of the cat states can be observed via the statistical distribution of quadrature. The real-time quadrature measurements are done by passing the electric signal of the homodyne detector through electrical low-pass filter, and the value of the voltage at the timing corresponds to generation of the cat states are taken as the quadrature values without any post processing.
