标题： Comment on "Experimental Test of Error-Disturbance Uncertainty Relations by Weak Measurement"

摘要： 在对F. Kaneda，S.-Y. Baek，M. Ozawa和K. Edamatsu的论文[Phys. Rev. Lett. 112, 020402, 2014, arXiv:1308.5868]的评论中，我们指出，声称已驳斥海森堡的误差-扰动关系是缺乏依据的，因为这是基于不合适的和操作上存在问题的测量误差和扰动的量化方法。 正如我们在其他地方所展示的[PRL 111, 160405, 2013]，对于适当的误差和扰动的操作性度量选择，海森堡的启发式关系可以转化为一个精确的不等式，这是量子力学的严格结果。 显示英文摘要

摘要： In this comment on the paper by F. Kaneda, S.-Y. Baek, M. Ozawa and K. Edamatsu [Phys. Rev. Lett. 112, 020402, 2014, arXiv:1308.5868], we point out that the claim of having refuted Heisenberg's error-disturbance relation is unfounded since it is based on the choice of unsuitable and operationally problematical quantifications of measurement error and disturbance. As we have shown elsewhere [PRL 111, 160405, 2013], for appropriate choices of operational measures of error and disturbance, Heisenberg's heuristic relation can be turned into a precise inequality which is a rigorous consequence of quantum mechanics.
