Long-range quantum correlations and entanglement in ultrafast multi-frequency comb systems

Abstract

We show how cascaded three-wave mixing processes between ultrafast pulses can enable a system of highly quantum correlated frequency combs spanning several octaves. This multi-comb system may be harnessed for quantum enhanced pump-probe spectroscopy.

Long-range entanglement in multimode comb systems via cascaded nonlinear processes

We show how cascaded nonlinear processes can enable a “comb of combs” that features entanglement both within and between different frequency combs, which may be harnessed for quantum enhanced multi-comb spectroscopy.

Long-range entanglement and quantum correlations in a multi-frequency comb system

Sahil Pontula, Debasmita Banerjee, Marin Soljacic +1 more

Frequency combs are multimode photonic systems that underlie countless precision sensing and metrology applications. Since their invention over two decades ago, numerous efforts have pushed frequency combs to broader bandwidths and more stable operation. More recently, quantum squeezing and entanglement have been explored in single frequency comb systems for quantum advantages in sensing and signal multiplexing. However, the production of quantum light across multiple frequency combs remains unexplored. In this work, we theoretically explore a mechanism that generates a series of nonlinearly coupled frequency combs through cascaded three-wave upconversion and downconversion processes mediated by a single idler comb. We show how this system generates inter- and intracomb two-mode squeezing and entanglement spanning a very large spectral range, from ultraviolet to mid-IR frequencies. Finally, we show how this system can be engineered to produce on-demand multimode quantum light through covariance matrix optimization. Our findings could enable tunable broadband ghost spectroscopy protocols, squeezing-enhanced pump-probe measurements, and broadband entanglement between spectrally-multiplexed quanta of information.
