摘要

We have designed a persistent supercurrent multi-Josephson junction (JJ) qubit whose circuit is based on a flattened JJ triangular prism. The Schrodinger equation for the ID constrained system is equivalent to the Whittaker Hill equation, for which exact solutions have been found [1]. Symmetric or antisymmetric coupling of the qubit to an external magnetic field. will excite only the corresponding symmetric or antisymmetric terms in the Hamiltonian. This specificity allows coupling to a system bus comprised of an LC resonant loop. We indicate how separate buses might be coupled into a larger branching network. Published by Elsevier Science B.V.
