美國能源部埃姆斯實驗室的科學家們發現，以一種週期性的方式應用振動運動有望避免電子態耗散，對於先進量子計算和自旋電子學技術發展可起到關鍵作用。
研究人員認為，這一發現將對材料在眾多科學和技術領域的應用產生深遠影響，比如量子信息、通信應用以及基於自旋的光波量子電子學。
Scientists at the U.S. Department of Energy's Ames Laboratory have discovered that applying vibrational motion in a periodic manner may be the key to preventing dissipations of the desired electron states that would make advanced quantum computing and spintronics possible.
Researchers believe the discovery has far-reaching consequences for the use of these materials to many scientific and technological disciplines, such as disorder-tolerant quantum information and communications applications and spin-based, lightwave quantum electronics.
