Mitigating Transients in Superconducting Quantum Processor Flux Control-Robots Talking Quantum EP 16
from Robots Talking Hosted by mstraton8112
Superconducting quantum processors commonly use flux-tunable components, but their dynamic control suffers from signal distortions and persistent transients. This paper models the flux control line as a simple RC circuit and introduces novel pulse designs to mitigate these long-time transients. The authors theoretically demonstrate the robustness of these pulses against parameter inaccuracies and experimentally validate their effectiveness in a flux-tunable qubit coupler. This work offers a practical and calibration-minimal solution for enhancing the reliability of quantum experiments by reducing unwanted signal artifacts
