Qiang Lin, an expert in integrated quantum photonics and nonlinear nanophotonics at the University of Rochester, is a recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE).

Physicist Andrew Jordan and his fellow researchers harnessed superconductivity to conceive of a quantum refrigerator that could cool atoms to nearly absolute zero temperatures.

For 90 years physicists have known that incompatibly opposite properties are inherent in all elementary particles. Now Rochester researchers say they’ve resolved this weird and inescapable wave-particle duality.

Optical physics and quantum optics will have a profound effect on our daily lives in the decades to come, and two Rochester faculty are among the authors of a new survey of the biggest scientific challenges and questions in the field.

Rochester researchers have created particles with negative mass in an atomically thin semiconductor, using a device that creates an optical microcavity.

For more than 30 years, researchers have been creating quantum dots—nanoscale semiconductors with remarkable properties. But quantum dot synthesis has occurred largely by trial and error. Thanks to the work of two Rochester chemists, that may be about to change.

Using the strange rules of quantum mechanics, researchers were able to put a quantum bit in a superposition of two different energy states at the same time in order to speed up the accurate measurement of frequencies.

Researchers have developed a “quantum enigma machine” to improve on data encryption. The device manipulates photons to create an unbreakable encrypted message with a key that’s far shorter than the message—the first time that has ever been done.

The best guide to the boundary between our everyday world and the “spooky” features of the quantum world has been a theorem called Bell’s Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.

Anton Zeilinger, one of the world’s leading experts in the field of quantum optics, will present a free, public lecture Tuesday at the University of Rochester. The talk is designed to convey the exciting frontiers of quantum mechanics to a general audience.
