Simulation and Analysis of Packaging of Superconducting Qubits

ORAL

Abstract

The superconducting qubit modality is a leading candidate today for the realization of a quantum information processor targeting first demonstrations of shallow depth quantum algorithms. The achievable circuit depth is limited in part by the lifetime of the constituent qubits. Although the lifetime of superconducting qubits has increased by several orders of magnitude over the last 15 years – largely due to improvements in design, materials, and fabrication methods – there is still need for further improvement. In this work, we present results from simulation and analysis of the materials and geometric effects related to qubit packaging and its impact on qubit lifetimes.
