Bluefors Helps University of Rochester Explore Higher-Dimensional Qudits

Associate Professor of Physics Machiel Blok and his research group at the University of Rochester are moving beyond the standard qubit by investigating superconducting qudits, quantum systems encoding information across multiple energy levels. Their work stems from the observation that many physical systems, including atoms and molecules, are not naturally binary, suggesting a potential efficiency gain by matching quantum hardware to the problems being simulated. According to Blok, “The holy grail of qudit research would be to build a simulator that maps the dimension of the information to the problem in nature, and then solves a problem that we actually care about.” The team’s focus on adapting existing superconducting circuits aims to unlock the benefits of these higher-dimensional systems for quantum simulation and error correction. The compact design of Bluefors’ cryogenic systems is particularly beneficial for the Rochester team, freeing up valuable laboratory space. “The compact system leaves more space for everything else. I can now dream of putting three, maybe even four dilution refrigerators in my lab. That really matters when space comes at a premium,” Blok explains.…
