美国能源部埃姆斯实验室的科学家们发现，以一种周期性的方式应用振动运动有望避免电子态耗散，对于先进量子计算和自旋电子学技术发展可起到关键作用。
研究人员认为，这一发现将对材料在众多科学和技术领域的应用产生深远影响，比如量子信息、通信应用以及基于自旋的光波量子电子学。
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.
