Experimental demonstration of multi-mode intensity squeezing in ~10 ps pulses via unbalanced SU(1,1) interferometers, achieving ~0.9 dB below shot noise for joint measurements over M>10 modes among 30 total modes.
Note we always have g(2)(0s, 0s) ! 2 since each signal or idler pulse is in single temporal mode

Generation of deterministic multi-mode intensity squeezing in a train of ultra-short pulses by unbalanced SU(1,1) interferometers
Experimental demonstration of multi-mode intensity squeezing in ~10 ps pulses via unbalanced SU(1,1) interferometers, achieving ~0.9 dB below shot noise for joint measurements over M>10 modes among 30 total modes.
