  bibo_abstract:
  - Multimode quantum light is enticing for several applications, spanning imaging,
    spectroscopy, communication, and more. Parametric nonlinear processes have been
    vital in realizing squeezed and other quantum states of light. However, most work
    exploiting these processes has focused on generating multimode squeezed vacua
    and squeezing in mode superpositions (supermodes). Bright squeezing in multiple
    discrete frequency modes, if realized, could unlock novel applications in quantum-enhanced
    spectroscopy and optical quantum computing. Here, we show how dissipation engineering
    of a multimode nonlinear cavity with cascaded three-wave-mixing processes allows
    us to shape above-threshold frequency combs that feature strong single-mode output
    amplitude noise squeezing over 10 dB below the shot-noise limit, tunable across
    the comb. In addition, we demonstrate squeezing for multiple discrete frequency
    modes above threshold. This bright squeezing arises from enhancement of the (noiseless)
    nonlinear rate relative to decay rates in the system due to the cascaded generation
    of photons in a single idler “bath” mode. A natural consequence of the strong
    nonlinear coupling in our system is the creation of an effective cavity in the
    synthetic frequency dimension that sustains Bloch oscillations in the modal energy
    distribution. Bloch mode engineering could provide an opportunity to better control
    nonlinear energy flow in the synthetic frequency dimension, with exciting applications
    in quantum random walks and topological photonics. Lastly, we show evidence of
    long-range correlations in amplitude noise between discrete frequency modes, enabling
    long-range entanglement in a synthetic frequency dimension and providing a new
    resource for quantum communication.@eng
