New method could yield fast, cross-country quantum network
Scientists have struggled to come up with practical methods of building networks that can connect quantum computers. Now, researchers at the University of Chicago have proposed a new approach — building long quantum channels using vacuum sealed tubes with an array of spaced-out lenses. These vacuum beam guides would have ranges of thousands of kilometers and capacities of 10 trillion qubits per second, better than any existing quantum communication approach. Read More

‘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

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
