Journal ArticleDOI
Process verification of two-qubit quantum gates by randomized benchmarking
Antonio Corcoles,Jay M. Gambetta,Jerry M. Chow,John A. Smolin,Matthew Ware,J.D. Strand,Britton Plourde,Matthias Steffen +7 more
TL;DR: In this paper, the authors implement a complete randomized benchmarking protocol on a system of two superconducting qubits, which consists of randomizing over gates in the Clifford group, which experimentally are generated via an improved two-qubit cross-resonance gate implementation and single qubit unitaries.
Journal ArticleDOI
First-order sideband transitions with flux-driven asymmetric transmon qubits
J.D. Strand,Matthew Ware,Félix Beaudoin,Thomas A. Ohki,Blake R. Johnson,Alexandre Blais,Britton Plourde +6 more
TL;DR: In this paper, the sideband transitions between a superconducting resonator and a frequency-modulated transmon qubit were demonstrated with a magnetic flux signal coupled to the qubit.
Journal ArticleDOI
Dynamical Superconducting Order Parameter Domains in Sr2RuO4
TL;DR: The presence of dynamical chiral order parameter domains of the form px ± ipy in the ruthenate superconductor Sr2 RuO4 confirms the p-wave triplet spin and complex (broken time-reversal symmetry) nature of the superconducting pairing state in Sr2RuO4.
Journal ArticleDOI
The transition between real and complex superconducting order parameter phases in UPt3.
TL;DR: The momentum space dependence of UPt3's superconducting gap as a function of temperature is measured; a real gap with line nodes was observed to develop first; then, at a lower critical temperature, a complex component appeared, with the total gap expected to become fully uniform at absolute zero.
Journal ArticleDOI
Evidence for complex superconducting order parameter symmetry in the low-temperature phase of UPt3 from Josephson interferometry.
TL;DR: The authors' corner junction data show asymmetric patterns with respect to magnetic field, indicating a complex order parameter, and both junction and SQUID measurements point to a phase shift of pi, supporting the E(2u) representation of the order parameter.
