JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) used quantum optics to advance state-of-the-art microscopy and, in doing so, chart a a path to detecting material properties with greater sensitivity than is possible with traditional tools. The quantum microscope uses nonlinear amplifiers to generate a special quantum light source known as squeezed light. “We showed how to use squeezed light — a workhorse of quantum information science — as a practical resource for microscopy,” said Ben Lawrie of ORNL’s...Read full articleRelated content from Photonics MediaArticlesSignal Sorting Method Suppresses Noise in STED MicroscopyResearchers from Zhejiang University have proposed a novel microscopy method that selectively and effectively suppresses background noise in the existing technique of stimulated emission depletion...BioPhotonics Sep/Oct 2022 IssueStructured Light Advancement Clears Way to Image Through Noisy ChannelsAn exciting prospect in modern optics is to exploit patterns of light — how the light looks in its many degrees of freedom — often referred to as “structured light.” Each...Photonics.com 2/16/2023Experiment Validates Stimulated Emission for Single PhotonsScientists at the University of Sydney and the University of Basel have demonstrated the ability to manipulate and identify small numbers of interacting photons with high correlation.
