要利用固态系统电子自旋的量子相干性,首先必须解决的一个问题就是由于与环境的耦合干扰而产生的自旋消相干.动力学解耦就是利用频闪的自旋反转与环境的平均耦合,其效果相当于与零耦合.这是对抗消相干的一种特
One of the first problems that must be solved to exploit the quantum coherence of electron spin in a solid-state system is spin-coherence due to coupling with the environment. Dynamic decoupling is the use of stroboscopic spin-reversals and the averaging of the environment Coupling, the effect is equivalent to coupling with zero. This is a special anti-coherent elimination
