Abstract: Abstract Arising from: H. Müller, A. Peters & S. Chu Nature 463, 926–929 (2010)10.1038/nature08776 ; Müller & Chu reply In ref. 1 the authors present a re-interpretation of atom interferometry experiments published a decade ago2. They now consider the atom interferometry experiments2 as a measurement of the gravitational redshift on the quantum clock operating at the Compton frequency ωC = mc2/ ≈ 2π × 3.0 × 1025 Hz, where m is the caesium (Cs) atom rest mass. They then argue that this redshift measurement compares favourably with existing3 as well as projected4 clock tests. Here we show that this interpretation is incorrect.
