Quantum-like nonlinear interferometry with frequency-engineered classical light
Quantum interferometry methods exploit quantum resources, such as photonic
entanglement, to enhance phase estimation beyond classical limits. Nonlinear
optics has served as a workhorse for the generation of entangled photon pairs,
ensuring both energy and phase conservation, but at the cost of limited rate
and degraded signal-to-noise ratio compared to laser-based interferometry
approaches. We present a "quantum-like" nonlinear optical method that reaches
super-resolution in single-photon detection regime. This is achieved by
replacing photon-pairs by coherent states of light, mimicking quantum
properties through classical nonlinear optics processes. Our scheme utilizes
two high-brightness lasers. This results in a substantially greater
signal-to-noise ratio compared to its quantum counterpart. Such an approach
paves the way to significantly reduced acquisition times, providing a pathway
to explore signals across a broader range of bandwidth. The need to increase
the frequency bandwidth of the quantum sensor significantly motivates the
potential applications of this pathway.
