WebNov 16, 2024 · Huh, the calculation is actually quite simple. I am surprised I didn't notice that earlier. By noticing that the trace of $\mathbf{e}\cdot\sigma$, $\forall \mathbf{e}\in \mathbb{R}^3$ is actually zero , and the following property: \begin{equation} \mathrm{tr}(A\otimes B)=\mathrm{tr}(A)\mathrm{tr}(B) \end{equation}. We can see that … There are many variations on the basic idea, some employing stronger mathematical assumptions than others. Significantly, Bell-type theorems do not refer to any particular theory of local hidden variables, but instead show that quantum physics violates general assumptions behind classical pictures of nature. The original theorem proved by Bell in 1964 is not the most amenable …
