Characterizing and Suppressing Noise in Superconducting Qubits and Qudits

ORAL · Invited

Abstract

Superconducting transmon qubits are key to recent quantum computing advances. This talk will present our recent work on characterizing the noise afflicting transmon qubits beyond standard stochastic error models. We'll then discuss quantum control methods to suppress this noise, aiming to improve gate fidelities and overall performance.
