论文摘要
尽管海森伯格的不确定性原则以量子状态的内在不确定性的严格证明的关系表示，但海森伯格的错误触及扰动关系（EDR）通常被认为是该原理的另一个方面。但是，量子测量理论的最新发展使海森伯格的EDR可检验以观察其违规行为。在这里，我们研究EDR进行船尾测量。在先前的报告[ARXIV：1910.07929]中，有人指出他们的EDR接近理论最佳。本说明报告说，即使是1922年的原始船尾 - 格拉赫实验，可用的实验数据也违反了海森伯格的EDR。结果表明，海森伯格的EDR比长期以来想象的更普遍的侵犯。
Although Heisenberg's uncertainty principle is represented by a rigorously proven relation about intrinsic indeterminacy in quantum states, Heisenberg's error-disturbance relation (EDR) has been commonly believed as another aspect of the principle. However, recent developments of quantum measurement theory made Heisenberg's EDR testable to observe its violations. Here, we study the EDR for Stern-Gerlach measurements. In a previous report [arXiv:1910.07929], it has been pointed out that their EDR is close to the theoretical optimal. The present note reports that even the original Stern-Gerlach experiment in 1922, the available experimental data show, violates Heisenberg's EDR. The results suggest that Heisenberg's EDR is more ubiquitously violated than it has long been supposed.
