Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

Bacteria can be evaluated in different plant root microenvironments (a) using microscope images of bacteria in root hairs with classical light (b) and using 100,000-fold lower quantum light colors (c) ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University of Iowa researchers found that unwanted photons produced by lasers can be ...

Imagine watching a time-lapse video of a garden you had filmed over the course of a year: you’d see details of flowers transitioning from day to night and season to season. Scientists would love to ...
