Building a Broader, More Secure Internet

George Siopsis has never shied away from bits and bytes and the way they work. He’s always seen their broad potential: from running calculations underpinning theoretical physics to the opportunities advanced computing holds for Appalachia. Working with colleagues from national labs, other universities, and the private sector, he’s playing a lead role in a multimillion-dollar project from the United States Department of Energy (DOE) to develop and expand secure quantum networks—a building block for new scientific infrastructure.

DOE recently announced a $61 million investment in quantum information science, including $25 million to create quantum internet testbeds. Siopsis, a professor in the physics department, is a co-principal investigator on one of the projects: Quantum-Accelerated Internet Testbed, or QuAInt. Nicholas Peters of Oak Ridge National Laboratory is the project lead, with deputy and co-PIs from Los Alamos National Laboratory, Purdue University, Amazon Web Services, and Qubitekk, founded by UT alumnus Duncan Earl. The goal is to devise, develop, and demonstrate a regional scale quantum internet testbed.
