论文摘要
我们使用船尾实验的修改设置提出了一种对自旋的状态估计方案，其中中性自旋1/2点颗粒的光束与四极磁场相互作用。提出的基于象限强度检测器的线性反转估计过程需要适当的梁初始空间状态。初始旋转状态的估计器的统计表征不仅使我们不仅可以将误差与估计参数相关联，而且还可以定义一个度量，以比较与不同的stern-gerlach设置相对应的估计过程。
We propose a state estimation scheme for spins, using a modified setup of the Stern-Gerlach experiment, in which a beam of neutral spin-1/2 point particles interacts with a quadrupolar magnetic field. The proposed linear inversion estimation procedure, based on a quadrant intensity detector, requires a suitable initial spatial state of the beam. The statistical characterization of the estimator of the initial spin state allows us not only to associate an error to the estimated parameters, but also to define a measure for comparing estimation procedures corresponding to different Stern-Gerlach setups.
