Experiments on Coupled Josephson Junction Devices
Abstract
This report results from a contract tasking University of Erlangen-Nuremberg as follows: The contractor will investigate coupled Josephson devices of two different kinds. First, the contractor will test a new concept of active antennas to couple radiation out from Josephson arrays. Using a mixed series-parallel array-biasing scheme, the contractor will design and perform waveguide-coupled emission experiments with single- and double-row arrays at 80-120 GHz. If successful, this scheme will be further implemented and tested using dipole antennas for the 400-500 GHz range. The contractor will also investigate the loop antenna array scheme as detailed in the technical proposal. The experiments will be done with Nb/Al- AOx/Nb Josephson junction arrays. The second Josephson device to be investigated (including design, fabrication, and testing) are novel q-bit devices. These q-bits are hoped to be more flexible and therefore more suitable hardware for quantum computing than single- loop SQUIDs currently pursued by other researcher groups. Full details are provided in the accompaning technical proposal.
