‘Quantum optical antennas’ provide more powerful measurements on the atomic level
From the University of Chicago: Researchers have never been able to tap the potentially huge intensity enhancements of some “atomic antennas” in solid materials simply because they were solids. Now, a multi-institutional team led by the University of Chicago's Alex High has cracked this problem. They have used germanium vacancy centers in diamonds to create an optical energy enhancement of six orders of magnitude, a regime challenging to reach with conventional antenna structures. 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
