部分交换、酉性和无信令
Partial Swapping, Unitarity and No-signalling
摘要：
众所周知，量子态$|ψ(θ,ϕ)>$由布洛赫球上的点表示，其特征在于两个参数$θ$和$ϕ$。在最近的工作中，我们已经证明了不可能部分交换这些量子参数。在这项工作中，我们将表明，这一不可能性定理是一致的原则，如量子力学的幺正性和无信号原则。
英文摘要：
It is a well known fact that an quantum state $|ψ(θ,ϕ)>$ is represented by a point on the Bloch sphere, characterized by two parameters $θ$ and $ϕ$. In a recent work we already proved that it is impossible to partially swap these quantum parameters. Here in this work we will show that this impossibility theorem is consistent with principles like unitarity of quantum mechanics and no signalling principle.
