评“弱测量误差-干扰不确定度关系的实验检验”

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

P. Busch, P. Lahti, R. F. Werner

摘要:

本文对F. Kaneda,S.- Y. Baek,M. Ozawa和K. Edamatsu [Phys. Rev. Lett. 112,020402,2014,arXiv:1308.5868],我们指出,反驳海森堡的误差-干扰关系的主张是没有根据的,因为它是基于测量误差和干扰的不合适的和操作上有问题的量化的选择。正如我们在其他地方所示[PRL 111,160405,2013],对于误差和扰动的操作度量的适当选择,海森堡的启发式关系可以转化为精确的不等式,这是量子力学的严格结果。

英文摘要:

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.
