We generate spectral multimode squeezed states and demonstrate quantum mode mixing, a method to arbitrarily mix the spectral multimode quantum states of light using a type-II PPLN waveguide, which is applicable to quantum simulators.

We generate 1.57-μm squeezed vacuum pulses by degenerate spontaneous parametric down conversion (DSPDC)and observe 3.5dB anti-squeezing and −0.48dB squeezing using local oscillator pulses generated from a degenerate synchronously pumped optical pa

We theoretically reveal the potential of the parallelism of squeezed state generation by nonlinear pulse propagation in an optical fiber. Starting from a nonlinear Schr\"odinger equation coupling with phonon modes that cause Raman noise, we develop a
