Modern Materials Engineering for High-Fidelity and Manufacturable Superconducting Qubits

Superconducting qubits are a promising platform for fault-tolerant quantum computers. Although there have been significant developments over the years, superconducting qubit hardware is currently limited by the qubit error rates and number of qubits. Error rates for superconducting qubits are typically dominated by material interface losses and defects.

Over the past decade, advanced CMOS manufacturing on 300 mm wafers has enabled significant innovation in the semiconductor industry for classical computing hardware. Superconducting qubit technology can leverage the capabilities developed for the semiconductor industry to improve qubit performance. In this talk, we present initial results towards fabricating superconducting qubits with improved interfaces using modern CMOS materials engineering methods.
