Qubit-State Purity Oscillations from Anisotropic Transverse Noise
David A. Rower, Kotaro Hida, Lamia Ateshian +13
We explore the dynamics of qubit-state purity in the presence of transverse noise that is anisotropically distributed in the Bloch-sphere XY plane. We perform Ramsey experiments wi…
Suppressing Counter-Rotating Errors for Fast Single-Qubit Gates with Fluxonium
David A. Rower, Leon Ding, Helin Zhang +12
Qubit decoherence unavoidably degrades the fidelity of quantum logic gates. Accordingly, realizing gates that are as fast as possible is a guiding principle for qubit control, nece…
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 --…
