In two celebrated experiments of quantum mechanics, the Stern-Gerlach (SG) and Heisenberg microscope (HM) experiments, the electron spin $s_z$ and spatial $\mathit{r}$ coordinates are measured separately. In this paper, the combined $\mathrm{SG}+\mathrm{HM}$ experiment is proposed to measure the full electron coordinate $\mathit{x}=\{\mathit{r},s_z\}$. To this end, noninterfering and (virtually) simultaneous SG and HM experiments are proposed to apply to the individual fragments A and B of an entangled dissociating system $\mathrm{A}\text{−}\mathrm{B}$. The theoretical description of a spin-collapsed and partially spatially collapsed state of the $\mathrm{SG}+\mathrm{HM}$ experiment is given for the prototype “perfectly” entangled system, the dissociating ${\mathrm{H}}_2$ molecule.

用于测量纠缠态全电子坐标的无干扰和同步 Stern-Gerlach 和 Heisenberg 显微镜实验

在两个著名的量子力学实验中，斯特恩-盖拉赫 (SG) 和海森堡显微镜 (HM) 实验中，电子自旋 ${秒}_z$ 和空间 $\mathit{r}$坐标分别测量。在本文中，结合$\mathrm{SG}+\mathrm{HM}$ 实验提出测量全电子坐标 $\mathit{X}=\{\mathit{r},{秒}_z\}$. 为此，建议将无干扰和（几乎）同时进行的 SG 和 HM 实验应用于纠缠解离系统的单个片段 A 和 B$\mathrm{一种}\text{-}\mathrm{乙}$. 自旋塌陷和部分空间塌陷状态的理论描述$\mathrm{SG}+\mathrm{HM}$ 对原型“完美”纠缠系统进行了实验，即解离系统 ${\mathrm{H}}_2$ 分子。
