Evaluating shielding strategies for improved qubit coherence using a rapid characterization cryostat
ORAL
Abstract
The performance of superconducting qubits is critically limited by decoherence processes influenced by magnetic and electromagnetic noise. We investigate the influence of different shielding configurations on the decoherence times of superconducting qubits within a fast-turnaround characterization cryostat.
Our study explores single- and double-layer shielding prototypes with various materials and surface coatings, systematically analyzing their combined effects on qubit relaxation and dephasing times. By characterizing qubit performance under controlled shielding scenarios, we aim to identify optimized designs that mitigate magnetic flux noise and improve environmental stability. This approach provides valuable insights into the design of compact, high-performance cryogenic environments for rapid and reliable quantum device testing, contributing to the broader goal of scalable, high-throughput qubit characterization for next-generation quantum technologies.
