Chicago Quantum Profile: Joe Heremans
From the Chicago Quantum Exchange: Joe Heremans is a staff scientist at Argonne National Laboratory, where he works on wide-bandgap solid-state materials systems with individual atomic defects. These defects “trap” an electron whose spin state can be manipulated with lasers, electric and strain fields, and microwaves. These systems have promising applications in quantum communication and sensing. Read More

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

Helium lifts new quantum computing concept
A team led by Jacob Covey, who is part of Q-NEXT and is an Associate Professor at the University of Chicago, laid out a new concept that could turn helium’s light weight into the next generation of quantum computers. The design relies on helium-3, an isotope with different quantum properties than the helium-4 used to cool MRI machines and fill party balloons. Once built, the computer could use high-powered lasers as “optical tweezers” to capture and control individual atoms of helium. Read More

Silicon Chip Offers New Way to Probe Quantum Materials in Strong Magnetic Fields
Scientists have created a silicon chip that can detect the electrical behavior of very small materials by using very high-frequency waves. The chip is made only from silicon and other non-superconducting materials and still performs very well when cooled from room temperature down to about 4 Kelvin. Read More
