Autonomous Time-Calibration for Quantum Dot Devices

Published:Dec 31, 2025 14:41
1 min read
ArXiv

Analysis

This paper addresses a critical challenge in scaling quantum dot (QD) qubit systems: the need for autonomous calibration to counteract electrostatic drift and charge noise. The authors introduce a method using charge stability diagrams (CSDs) to detect voltage drifts, identify charge reconfigurations, and apply compensating updates. This is crucial because manual recalibration becomes impractical as systems grow. The ability to perform real-time diagnostics and noise spectroscopy is a significant advancement towards scalable quantum processors.
Reference

“The authors find that the background noise at 100 μHz is dominated by drift with a power law of 1/f^2, accompanied by a few dominant two-level fluctuators and an average linear correlation length of (188 ± 38) nm in the device.”
