Quantum light squeezes the noise out of microscopy signals

Quantum light squeezes the noise out of microscopy signals

"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 Materials Science and Technology Division, who led the research with Raphael Pooser of ORNL's Computational Sciences and Engineering Division. "We measured the displacement of an atomic force microscope microcantilever with sensitivity better than the standard quantum limit."
