Toward an ultra-high fidelity and scalable fluxonium quantum processor

ORAL

Abstract

Fluxonium qubits are promising candidates for next-generation superconducting quantum processors due to their long coherence time and large anharmonicity. Moreover, fluxonium can be directly integrated into the existing circuit-QED schemes for quantum computing. In this talk, we present our design and experiments of a 2D multi-qubit fluxonium circuit in a scalable, high-fidelity quantum processor. The processor features tunable qubits with individual high-bandwidth fast control, which facilitates the demonstration of the circuit’s high-fidelity reset, gates, and readout. We believe that such processors will enable ultra-high fidelity quantum information processing through a scalable multi-qubit system.
