Using quantum data to create an unhackable Internet: ‘We’re getting close,’ University of Chicago expert leading project says
From the Chicago Sun-Times: University of Chicago scientists are working on creating what once might have seemed like science fiction: an unhackable internet. The Chicago quantum network project involves a test bed of 124 miles of underground fiber-optic cable that links the university with Argonne National Laboratory in Lemont and Fermilab in Batavia.

Chicago scientists are testing an unhackable quantum internet in their basement closet
From The Washington Post: A 124-mile fiber-optic network runs from the University of Chicago on Chicago’s South Side to two federally funded labs in the western suburbs that are collaborating on the research — Argonne National Laboratory and Fermi National Accelerator Laboratory. The team behind the network is using photons to dispatch encryption keys through the network, to see how well they travel through fibers that pass under highways, bridges and toll booths. 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

Researchers make materials that support quantum technology
Researchers from the University of Illinois Urbana-Champaign who are part of Q-NEXT are engineering material systems that support quantum technology. Chris Anderson and his team are developing materials for quantum transduction — the conversion of quantum information from one form to another. Elizabeth Goldschmidt, Daniel Shoemaker, and colleagues are developing quantum memory technology that stores quantum information for extended periods of time. 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
