- We comment on the significance of the results in the paper by Nakamura et al (2020). The experimental result measures the phase for a repeated elementary exchange of two identical quasiparticles, and shows that the quasiparticles are anyons. The value of the phase agrees with theoretical predictions. However, in terms of the statistics parameter $θ$ for a single elementary exchange, it determines $2θ$ modulo $2π$, and hence $θ$ only modulo $π$, not modulo $2π$, and so does not fully check the theoretical prediction for the braiding statistics of charge $e/3$ quasiparticles. This is a general shortcoming of this particular type of interference measurement of statistics.
