Fast Microwave-free State Preparation and Measurement of Superconducting Qubits
R. Abraham, F. Amet, P. Anderson +212
Fast, high-fidelity, scalable state preparation and measurement is critical to the realization of a quantum computing system. The state-of-the-art methods for preparation and reado…
Fast, Lifetime-Preserving Readout for High-Coherence Quantum Annealers
Jeffrey A. Grover, James I. Basham, Alexander Marakov +15
We demonstrate, for the first time, that a quantum flux parametron (QFP) is capable of acting as both isolator and amplifier in the readout circuit of a capacitively shunted flux q…
First-order sideband transitions with flux-driven asymmetric transmon qubits
J. D. Strand, Matthew Ware, Félix Beaudoin +4
We demonstrate rapid, first-order sideband transitions between a superconducting resonator and a frequency-modulated transmon qubit. The qubit contains a substantial asymmetry betw…
Process verification of two-qubit quantum gates by randomized benchmarking
A. D. Córcoles, Jay M. Gambetta, Jerry M. Chow +5
We implement a complete randomized benchmarking protocol on a system of two superconducting qubits. The protocol consists of randomizing over gates in the Clifford group, which exp…
Alignment of chiral order parameter domains in Sr_{2} RuO_{4} by magnetic field cooling
Francoise Kidwingira, Joel D. Strand, D. J. Van Harlingen +1
Superconductivity in SrRuO is unconventional, believed to be of pairing symmetry. These two degenerate order parameters allow the formation of chiral…
Evidence for the E_2u model of the superconducting order parameter in UPt_3 from Josephson interferometry
J. D. Strand, D. J. Van Harlingen, J. B. Kycia +1
We present data on the modulation of the critical current with applied magnetic field in UPt_3-Cu-Pb Josephson junctions and SQUIDs. The junctions were fabricated on polished surfa…
