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

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.

New doors opening: UChicago programs aim to help build the quantum workforce of the future
From the University of Chicago: Teaching quantum concepts early is key to sparking students' interest, but the newness of the field also means that quantum isn't currently part of most high school and undergraduate science curricula. Three outreach programs at the UChicago Pritzker School of Molecular Engineering, designed to expose a wide range of students to quantum, are changing the landscape. Read More
