可观测量不互补的King问题的解

Solution to the King's problem with observables being not mutually complementary

Minoru Horibe, Akihisa Hayashi, Takaaki Hashimoto

摘要:

本文研究了用算符$\vec{n}_k \nobreak \cdot \nobreak \vecσ (k=1,2,3)$代替自旋算符$\vecσ$的三个笛卡尔分量$σ_x$、$σ_y$和$σ_z$的测量的King问题.这里,$\vec{n}_k$是三维实单位向量。我们证明了三个向量$\vec{n}_k$上的条件,以确定这些算子中任何一个的测量结果。

英文摘要:

We investigate the King's problem of the measurement of operators $\vec{n}_k \nobreak \cdot \nobreak \vecσ (k=1,2,3)$ instead of the three Cartesian components $σ_x$, $σ_y$ and $σ_z$ of the spin operator $\vecσ$. Here, $\vec{n}_k$ are three-dimensional real unit vectors. We show the condition over three vectors $\vec{n}_k$ to ascertain the result for measurement of any one of these operators.
