Abstract

We present the first bright amplitude-squeezed frequency comb using an on-chip Si3N4 optical parametric amplifier. We demonstrate 6 pairs of two-mode-squeezed states (12 qumodes) with a maximum 4 dB of directly detected quantum noise reduction.

Highly squeezed nanophotonic quantum microcombs with broadband frequency tunability

Yichen Shen, Ping‐Yen Hsieh, Dhruv Srinivasan +8 more

Squeezed light offers genuine quantum advantage in enhanced sensing and quantum computation; yet the level of squeezing or quantum noise reduction generated from nanophotonic chips has been limited. In addition to strong quantum noise reduction, key desiderata for such a nanophotonic squeezer include frequency agility or tunability over a broad frequency range, and simultaneous operation in many distinct, well-defined quantum modes (qumodes). Here we present a strongly overcoupled silicon nitride squeezer based on a below-threshold optical parametric amplifier (OPA) that produces directly detected squeezing of 5.6 dB $\pm$ 0.2 dB, surpassing previous demonstrations in both continuous-wave and pulsed regimes. We introduce a seed-assisted detection technique into such nanophotonic squeezers that reveals a quantum frequency comb (QFC) of 16 qumodes, with a separation of 11~THz between the furthest qumode pair, while maintaining a strong squeezing. Additionally, we report spectral tuning of a qumode comb pair over one free-spectral range of the OPA, thus bridging the spacing between the discrete modes of the QFC. Our results significantly advance both the generation and detection of nanophotonic squeezed light in a broadband and multimode platform, establishing a scalable, chip-integrated path for compact quantum sensors and continuous-variable quantum information processing systems.

Deterministic quantum regime is an unexplored aspect of the optical microresonator-based frequency comb (microcomb). We report a deterministic quantum microcomb in a silica microresonator on a silicon chip by measuring two-mode squeezed comb mode pairs. A maximum raw squeezing of 1.6 dB is attained.

Strong squeezing from seed-assisted parametric amplification and its gain dependence in SiN microresonators

Yichen Shen, Ping‐Yen Hsieh, Dhruv Srinivasan +5 more

We demonstrate bright two-mode squeezed states generated in silicon nitride microresonators using integrated seed-assisted optical parametric amplification (OPA). This integrated quantum source produces a bright squeezed quantum frequency comb spanning multiple mode pairs with frequency separations up to 11 THz, and achieves up to 5.6 dB of measured intensity-difference squeezing. We systematically explore how pump and seed detunings, gain and phase-matching conditions of nonlinear interaction influence squeezing performance. These factors extend beyond conventionally known squeezed-state-degradation with optical losses, impacting the achievable squeezing in integrated microresonators. These insights advance the fundamental understanding necessary for practical integrated quantum photonic devices, paving the way toward robust, scalable applications in quantum information processing and quantum-enhanced sensing.

Multipartite quantum correlated bright frequency combs

Adrien Bensemhoun, S. Cassina, C. Gonzalez-Arciniegas +12 more

This experimental work demonstrates multipartite quantum correlation in bright frequency combs out of a microresonator integrated on silicon nitride operating above its oscillation threshold. Multipartite features, going beyond so far reported two-mode correlation, naturally arise due to a cascade of nonlinear optical processes, making a single-color laser pump sufficient to initiate their generation. Our results show the transition from two-mode to multipartite correlation, witnessed by noise reductions as low as − 2.5 dB and − 2 dB , respectively, compared to corresponding classical levels. A constant of the movement of the nonlinear interaction Hamiltonian is identified and used to asses the multipartite behavior. Reported demonstrations pave the way to next generation on-chip multipartite sources for quantum technologies applications.
