The problem...is that finite precision might imply that in practice no two experimental procedures are found to be operationally equivalent.... A possible resolution of this finite precision loophole is to further generalize the definition..." | |

It seems a better starting point for discussion than arxiv.com/abs/1006.0500, which at a glance seems slightly idiosyncratic. The definition of operational equivalence in section II seems problematic, however, because of its reliance on the phrase "every possible measurement procedure", insofar as advances in Physics precisely depend on previously unconceived measurement procedures. Particularly if we devote all our effort to discriminating one preparation apparatus from another. Absolutely identical? | |
