TLDR
The direct measurement of 15 dB squeezed vacuum states of light and their application to calibrate the quantum efficiency of photoelectric detection and a customized InGaAs positive intrinsic negative photodiode optimized for high external quantum efficiency are reported on.Abstract:
Researchers have created quantum states of light whose noise level has been ``squeezed'' to a record low.read more

Reconstructing Gaussian bipartite states with a single polarization-sensitive homodyne detector.
TL;DR: In this article , a single homodyne detector was proposed to estimate Gaussian bipartite polarization states using only a single detector, which circumvents additional optics, and thereby losses, in the signal path.
