The standard limit on the precision with which a quantum measurement can be carried out is due to the statistical error associated with counting discrete particles rather than continuous quantities.

量子测量中精度的标准极限，源于与可计数离散粒子，而不是连续量相关的统计误差。

What really interest me about this is that, entirely independently, the same explanation is made for the measurement error here.

But the implications of this had, to date, "not been well-presented to government, nor have issues of measurement error and the implications these have for performance tables".

"The scientists are right to be extremely cautious about interpreting these findings, " said Jim Al-Khalili, a physicist from the University of Surrey, who suggested that a simple error in the measurement is probably the source of all the fuss.
