Characterization and Comparison of Energy Relaxation in Fluxonium Qubits

Kate Azar, Lamia Ateshian, Mallika T. Randeria +19

Fluxonium superconducting qubits have demonstrated long coherence times and high single- and two-qubit gate fidelities, making them a favorable building block for superconducting q…

Improving Transmon Qubit Performance with Fluorine-based Surface Treatments

Michael A. Gingras, Bethany M. Niedzielski, Kevin A. Grossklaus +21

Reducing materials and processing-induced decoherence is critical to the development of utility-scale quantum processors based on superconducting qubits. Here we report on the impa…

Dephasing in Fluxonium Qubits from Coherent Quantum Phase Slips

Mallika T. Randeria, Thomas M. Hazard, Agustin Di Paolo +12

Phase slips occur across all Josephson junctions (JJs) at a rate that increases with the impedance of the junction. In superconducting qubits composed of JJ-array superinductors --…
