Abstract:

We have designed a persistent supercurrent multi-Josephson junction JJ qubit whose circuit is based on a flattened JJ triangular prism. The Schroedinger equation for the 1D 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.
