The effect of magnetic field on the intrinsic detection efficiency of superconducting single-photon detectors
J. J. Renema, R. J. Rengelink, I. Komen +11
We experimentally investigate the effect of a magnetic field on photon detection in superconducting single-photon detectors. At low fields, the effect of a magnetic field is throug…
Critical-Current Reduction in Thin Superconducting Wires Due to Current Crowding
H. L. Hortensius, E. F. C. Driessen, T. M. Klapwijk +2
We demonstrate experimentally that the critical current in superconducting NbTiN wires is dependent on their geometrical shape, due to current-crowding effects. Geometric patterns…
One- and two-photon spectroscopy of a flux qubit coupled to a microscopic defect
A. Lupascu, P. Bertet, E. F. C. Driessen +2
We observed the dynamics of a superconducting flux qubit coupled to an extrinsic quantum system (EQS). The presence of the EQS is revealed by an anticrossing in the spectroscopy of…
