相对信息的量子估计
Quantum estimation of relative information
摘要：
我们推导出两个量子系统之间的关系自由度的准备和估计的最佳方案。我们具体分析了旋转参数代表SU（2）对称群元素之间的相对角度的情况。我们的估计过程不假设系统的绝对空间方向的先验知识，因此不需要关于准备状态的基本经典参考系的信息。
英文摘要：
We derive optimal schemes for preparation and estimation of relational degrees of freedom between two quantum systems. We specifically analyze the case of rotation parameters representing relative angles between elements of the SU(2) symmetry group. Our estimation procedure does not assume prior knowledge of the absolute spatial orientation of the systems and as such does not require information on the underlying classical reference frame in which the states are prepared.
