Geometrical dependence of the low-frequency noise in superconducting flux qubits

Article reporting on a study of a series of 85 devices of vary design using a general method for directly measuring the low-frequency flux noise (below 10 Hz) in compound Josephson-junction superconducting flux qubits. The results support the hypothesis that local impurities in the vicinity of the qubit wiring are a key source of low-frequency flux noise in superconducting devices.

Interrogating vertically oriented carbon nanofibers with nanomanipulation for nanoelectromechanical switching applications (open access)

Interrogating vertically oriented carbon nanofibers with nanomanipulation for nanoelectromechanical switching applications

Article demonstrates electrostatic switching in vertically oriented carbon nanofibers synthesized on refractory metallic nitride substrates, where pull-in voltages Vpi ranged from 10 to 40 V. A finite element model was also developed to determine a theoretical Vpi and results were compared to experiment.
