摘要: An improved tunable coupling element for building networks of coupled rf-superconducting quantum interference device rf-SQUID flux qubits has been experimentally demonstrated. This new form coupler, based on the compound Josephson-junction rf-SQUID, provides a sign and magnitude mutual inductance between with minimal nonlinear crosstalk from coupler tuning parameter into qubits. Quantitative agreement is shown an effective one-dimensional model coupler’s potential measurements persistent current susceptibility.
