... Einstein argued that quantum mechanics is incomplete. Note that [x, ˆp] ≠ 0, but [x2–x1, pˆ 2+pˆ 1] = [x2, pˆ 2] – [x1, pˆ1] = 0. That means we can measure the distance between two particles and their total momentum, to arbitrary precision. So we can measure either x2 or p2 without affecting Particl ...

Introduction to the Fractional Quantum Hall Effect
... In the so-called integer quantum Hall effect (IQHE) discovered by von Klitzing in 1980, the quantum number ν is a simple integer with a precision of about 10−10 and an absolute accuracy of about 10−8 (both being limited by our ability to do resistance metrology). In 1982, Tsui, Störmer and Gossard ...
