Solution phase correlation spectroscopy for ultrafast characterization of single photon emitters
A long-standing issue that limits the systematic improvement of single quantum emitters (SQEs) is the significant sample heterogeneity and consequent selection bias in choosing SQEs for characterization. To tackle this challenge, a spectroscopic method that can obtain sample-averaged performances with statistical significance is a prerequisite. Read More

Scientists turn a nanowire with exotic currents into a probe for magnetism
From UIUC: A team of researchers led by Vidya Madhavan at the University of Illinois Urbana-Champaign added a twist to their scanning tunneling microscope by replacing the tip with a nanowire made from an exotic material. They use the nanowire to image magnetic features in an approach that has potential advantages compared to other methods. The team plans to modify the nanowire to see if it can reveal even more material features or, for example, detect particles called Majorana fermions, which have long been proposed as the basis for novel quantum computing devices.

Quantum innovation at HRL Laboratories
In 1960, Hughes Research Laboratories demonstrated the world’s first laser. It was a breakthrough born of the laboratory’s cutting-edge capabilities in photonics and materials science. Over the last decade, the Malibu-based research lab — now named HRL Laboratories — has been applying those same capabilities to quantum information science. A Q-NEXT industry partner, HRL is helping the center develop the technologies needed to realize quantum communication. Read More
