Quantum Error Correction of Bosonic Qudits Beyond Break-even

Explore quantum error correction techniques for bosonic qudits in this 32-minute conference talk presented by Benjamin Brock from Yale University at the QuDits for Quantum Technology workshop. Delve into the importance of Hilbert space dimension in quantum information processing and its role in quantum error correction. Discover the first experimental demonstrations of error-corrected logical qutrits (d=3) and ququarts (d=4) using the Gottesman-Kitaev-Preskill (GKP) bosonic code in a circuit QED architecture. Learn about the optimization of GKP qutrit and ququart as ternary and quaternary quantum memories using a reinforcement learning agent, achieving beyond break-even error correction. Gain insights into new research directions for quantum information processing with bosonic qudits and understand the significance of these advancements in the field of quantum computing.
