This study systematically catalogs the design space of nonlinear superconducting circuits up to five nodes, identifying unique Hamiltonian classes and highlighting novel three-node configurations for qubit applications. By exhaustively analyzing combinations of capacitors, inductors, and Josephson junctions, the research provides a foundational reference for discovering previously unexplored circuit architectures essential for quantum hardware advancement.
Enumeration of all superconducting circuits up to 5 nodes
arXiv:2410.18497v2 Announce Type: replace Abstract: Nonlinear superconducting circuits can be used as amplifiers, transducers, and qubits. Only a handful have been analyzed or built, so useful configurations likely remain undiscovered. In this paper, we enumerate all unique nonlinear superconducting circuits, up to five nodes in size, built of capacitors, inductors, and Josephson junctions. We catalog the resulting design space by sorting circuits into "Hamiltonian classes" using a set of reference coordinates. Finally, we search for novel superconducting qubits by explicitly considering all three-node circuits, showing how the results of our enumeration can be used as a starting point for circuit design tasks.
