Nonlinear interferometers with correlated photons: toward spectroscopy and imaging with quantum light.

Published in: Light, science & applications (2020)

A nonlinear optical interferometer based on crystal superlattices has been demonstrated for the first time in a cascade of up to five crystals. The enhanced sensitivity due to quantum interference and correlations makes it a promising tool for sensing, imaging, and spectroscopy.
