TLDR
In this paper, the authors used squeezed light to track the constituents of yeast cells with a performance that overcomes the quantum noise limit, which allows for the utilization of low optical power, which helps to minimize cell damage.

Degenerate squeezing in a dual-pumped integrated microresonator: parasitic processes and their suppression

TL;DR: In this article, a dual-pump four-wave mixing configuration was considered and the effects of parasitic quantum nonlinear optical processes on the generation of degenerate quadrature squeezing was investigated.

Robust squeezed light against mode mismatch using a self imaging optical parametric oscillator

TL;DR: In this article, the authors presented a self-imaging optical parametric oscillator that is robust against spatial mode mismatch (beam displacement, tilt, and beam size difference) and showed that the generated light is more robust to mode mismatch than single-mode squeezed light having the same level of squeezing.

Quantum-enhanced measurements: beating the standard quantum limit.

TL;DR: This work has shown that conventional bounds to the precision of measurements such as the shot noise limit or the standard quantum limit are not as fundamental as the Heisenberg limits and can be beaten using quantum strategies that employ “quantum tricks” such as squeezing and entanglement.
