Comment on "Matter-Wave Interferometry of a Levitated Thermal   Nano-Oscillator Induced and Probed by a Spin"
  In this comment, we agree with the formulas derived in Refs. [1,2] but show that the results are not due to "interference between spatially separated states of the center of mass of a mesoscopic harmonic oscillator".
