Flux Sweeper System
Case ID:
050-9265
Web Published:
9/5/2024
Background
As quantum computing technologies advance, managing magnetic flux becomes increasingly critical. Magnetic flux trapping is a persistent challenge that can degrade the performance of superconducting circuits, potentially leading to malfunction. Traditional methods for expelling magnetic flux, such as repeated thermal cycling or applying strong decaying alternating current magnetic pulses, are often time-consuming and energy-intensive. Innovative techniques for efficiently managing and mitigating magnetic flux are essential to ensure the continued progress of quantum computing technology.
Technology
Inventors at Stony Brook University have developed a groundbreaking system for the effective management and removal of trapped magnetic flux in superconducting circuits. This innovative system significantly enhances the performance of superconducting digital circuits by creating temperature gradients during thermal cycling, which efficiently expel residual magnetic flux. The system utilizes PCB traces as thermal links to deliver heat from the heating fixtures to the heating elements, resulting in a non-uniform temperature distribution that sweeps trapped flux away from magneto-sensitive areas.
