Dephasing in tunable Xmon transmon qubits
ORAL
Abstract
One of the key challenges in superconducting qubits is maintaining coherent control during operation. For our frequency-tunable architecture, the environment at a broad range of frequencies becomes relevant for the success rate of quantum algorithms. I will present Carr-Purcell-Meiboom-Gill measurements aimed at identifying phase noise and its contribution to gate error away from the flux-insensitive point.
