Enabling technologies for increased circuit complexity of high-coherence superconducting qubits: Part 1

ORAL

Abstract

Air bridge crossovers are an enabling technology for high-coherence superconducting qubit circuits that provide an additional routing layer to increase circuit complexity. MIT Lincoln Laboratory also has integrated superconducting crossovers into high-coherence superconducting qubits and used them to increase coupling strength between qubits by facilitating coplanar, interwoven qubit loops with large mutual inductances. Here we will describe further development of crossovers with a broad range of simultaneously patterned air bridge lengths and corresponding characterization of the crossovers.
