Dependence of measured audio-band squeezing level on local oscillator intensity noise.
TL;DR: The theoretical results indicate that the measured squeezing level produces a large measurement error with the increase of the LO intensity noise, but the measurement error has immunity to the product P of the common mode rejection ratio (CMRR) with theLO intensity noise.

Spatiotemporal graph states from a single optical parametric oscillator
TL;DR: In this paper, an experimental scheme for building massively multipartite entangled states using both the spatial and the frequency modes of an optical parametric oscillator was proposed, which can generate, in parallel, several cluster states described by sparsely connected, bicolorable graphs.

Quantum Enhanced Precision Estimation of Transmission with Bright Squeezed Light
TL;DR: In this article, the authors demonstrate simultaneous enhancement of precision and sensitivity to beyond the quantum noise limit for estimating modulated transmission with a squeezed amplitude probe of $0.2$ mW average power, which is 8 orders of magnitude above the power limitations of previous sub-QNL precision measurements of transmission.

TL;DR: This work makes a measurement system and uses it to demonstrate basic quantum operations multiplexed in the time domain with 25 MHz clock frequency, and verifies transformations of the input states and their nonclassicalities for single-step quantum operations and also observes multi- step quantum operations up to one hundred steps.
