Microstrip filters for measurement and control of superconducting qubits
Luigi Longobardi, Douglas A. Bennett, Vijay Patel +2
Careful filtering is necessary for observations of quantum phenomena in superconducting circuits at low temperatures. Measurements of coherence between quantum states requires exte…
Experimental Study of Resistive Bistability in Metal Oxide Junctions
Zhongkui Tan, Vijay Patel, Konstantin K. Likharev +2
We have studied resistive bistability (memory) effects in junctions based on metal oxides, with a focus on sample-to-sample reproducibility which is necessary for the use of such j…
Decoherence in rf SQUID Qubits
Douglas A. Bennett, Luigi Longobardi, Vijay Patel +3
We report measurements of coherence times of an rf SQUID qubit using pulsed microwaves and rapid flux pulses. The modified rf SQUID, described by an double-well potential, has inde…
Temperature Dependence of Critical Current Fluctuations in Nb/AlO/Nb Josephson Junctions
Shawn Pottorf, Vijay Patel, James E. Lukens
We have measured the low frequency critical current noise in Nb/AlO/Nb Josephson junctions. Unshunted junctions biased above the gap voltage and resistively shunted…
Crossover from Kramers to phase-diffusion switching in hysteretic DC-SQUIDs
J. Mannik, S. Li, W. Qiu +4
We have measured and propose a model for switching rates in hysteretic DC-SQUID in the regime where phase diffusion processes start to occur. We show that the switching rates in th…
Universal distribution of transparencies in highly conductive Nb/AlO/Nb junctions
Y. Naveh, Vijay Patel, D. V. Averin +2
We report the observation of the universal distribution of transparencies, predicted by Schep and Bauer [Phys. Rev. Lett. {\bf 78}, 3015 (1997)] for dirty sharp interfaces, in unif…
