Developing Quantum Nano‐Wire (non‐tunnel‐junction) Based Superconducting Qubits

Koch and a graduate student (funded at 50%) will provide theory support for the proposed research. Koch will direct efforts focused on elucidating the theoretical underpinnings of superconducting circuits based on phase-slip junctions, and investigate their prospects for protected-qubit design. Koch will mentor and guide the graduate student carrying out the concrete tasks of detailed analytical modeling and numerical simulation of these novel circuits, including the determination of spectral properties, prediction of coherence times, and development/optimization of control and readout protocols.
