AI Technical Summary
In existing technologies, optical fibers are prone to length fluctuations due to changes in ambient temperature, which affects the stability of quantum bit storage.
A composite thermal insulation structure consisting of a vacuum insulator and a thermal insulation layer, combined with multiple layers of thermal insulation buffer and liquid buffer, forms a multi-layered thermal insulation protection that blocks the impact of ambient temperature fluctuations on quantum optical fibers.
It effectively suppressed the length fluctuation of quantum optical fiber caused by temperature changes, ensuring the stability and consistency of quantum bit storage, and achieving high-stability temperature control with a temperature change rate of no more than 0.01℃ per hour.
