A new compiler, which converts human-readable code to the explicit instructions that computing machinery, classical or quantum, need to operate, received one of seven Distinguished Paper awards this month at the 2021 Symposium on Principles of Programming Languages (POPL), one of the top conferences in programming languages research. VOQC, developed by UChicago CS assistant professor Robert Rand and collaborators at the University of Maryland, is the first verified quantum optimizer — a tool for rewriting programs to make them faster while guaranteeing that the program’s meaning is preserved.

Working with theorists in the University of Chicago’s Pritzker School of Molecular Engineering, researchers in the U.S. Department of Energy’s (DOE) Argonne National Laboratory have achieved a scientific control that is a first of its kind. They demonstrated a novel approach that allows real-time control of the interactions between microwave photons and magnons, potentially leading to advances in electronic devices and quantum signal processing.

Despite incredible promise, the quantum architectures available today remain limited in scale and handicapped by error and noise, falling short thus far of the killer app that would launch a new era of computing. With a new NSF CAREER Award, UChicago Computer Science Assistant Professor Bill Fefferman will pursue the theory and algorithms needed to leap this hurdle.
Chicago Quantum Exchange
December 18, 2020
Quantum information science had a banner year in the U.S. with federal agencies awarding more than $700M to support large-scale scientific endeavors, significant advancements in quantum information science, and the launch of programs that will help the nation retain global leadership in this critical field. During 2020, Chicago Quantum Exchange members and scientists were awarded new federal centers and institutes, made advances in quantum science, added 13 new corporate partners, and initiated new programs to prepare a quantum workforce.

This month, scientists at Fermilab, a U.S. Department of Energy Office of Science national laboratory, and their partners took a significant step in the direction of realizing a quantum internet.
In a paper published in PRX Quantum, the team presents for the first time a demonstration of a sustained, long-distance (44 kilometers of fiber) teleportation of qubits of photons (quanta of light) with fidelity greater than 90%. The qubits were teleported over a fiber-optic network using state-of-the-art single-photon detectors and off-the-shelf equipment.
