Briefings

Researchers at the University of Rochester, led by Associate Professor Machiel Blok, are investigating superconducting qudits as a potential alternative to binary qubits for quantum computing. The study focuses on using multiple energy levels to better simulate complex physical systems like quantum chemistry and field theory, aiming to match the natural dimensionality of nature. A key achievement reported is the development of a new control method that efficiently drives transitions between multiple energy levels simultaneously, addressing the inefficiency of traditional level-by-level control. The research also explores applications in quantum error correction and seeks to understand how information behaves in higher-dimensional systems.

Key points

• Researchers at the University of Rochester, led by Associate Professor Machiel Blok, are investigating superconducting qudits to explore higher-dimensional quantum systems for quantum simulation and error correction.
