Optimizing the generation of polarization squeezed light in nonlinear optical fibers driven by femtosecond pulses
TL;DR: In this paper , a two-mode polarization squeezing method was proposed to generate light in optical fibers utilizing the Kerr effect for ultrashort laser pulses, which is SU(2)-invariant, robust against technical perturbations, and can be generated in a polarization-maintaining fiber.

Quantum-enhanced stimulated Raman scattering
TL;DR: In this article , the classical probe beam was replaced by a quantum probe beam, allowing an enhancement in sensitivity beyond the shot noise limit, and the quantum resources can be used to enhance the sensitivity in systems that cannot be improved by simply increasing the optical power.
