Beyond Binary Quantum Information: Controlling the Excited States of Artificial Atoms in Superconducting Circuits

Watch a 49-minute lecture exploring the advanced concepts of quantum information processing beyond binary states, focusing on controlling excited states of "artificial atoms" in superconducting circuits. Learn about encoding quantum information in higher energy levels of the transmon circuit as a resource-efficient method for controlling large Hilbert spaces and executing quantum algorithms with reduced circuit complexity. Discover recent developments from UC Berkeley's qu-trit quantum processor and ongoing research at the University of Rochester, including the preparation and readout of Fock states up to ten microwave photons. Understand how the strong Kerr non-linearity of the transmon enables non-Gaussian operations that are difficult to achieve in a linear mode. Explore the potential benefits of this approach for bosonic quantum error correction and qu-dit simulation, presented by Dr. Machiel Blok, an Assistant Professor at the University of Rochester and former researcher at Delft University of Technology/QuTech and UC Berkeley.
