我们提出了现实的方法来检测本地自旋极化，利用量子点耦合到目标系统的一面。通过选择适当的量子点状态，我们可以对量子点施加自旋选择性，在小扰动下探测目标的自旋。我们还提出了一个实验，实现了一个建议的自旋检测方案在磁场中。
We propose realistic methods to detect local spin polarization, which utilize a quantum dot side coupled to the target system. By choosing appropriate states in the dot, we can put spin selectivity to the dot and detect spins in the target with small disturbance. We also present an experiment which realizes one of the proposed spin-detection schemes in magnetic fields.
