From Max Wallis, Cardiff Centre for Astrobiology, University of Cardiff
The match between theory and experiment in the buckyball diffraction experiment is pretty poor (15 May, p 30). According to the original paper in Nature (vol 427, p 711), the curve describing Anton Zeilinger’s quantum decoherence theory passes under many of the data points.
Scientifically one needs to assess whether the measurements distinguish his decoherence theory from other possible theories. The original paper does not attempt that.
