Recently in Phys. Rev. D 99, 104010 (2019), the nonrelativistic Feynman propagator for a harmonic oscillator system was presented when the generalized uncertainty principle is employed. In this short Comment we show that the expression is incorrect, and we derive its correct form.

Short, A. J.

Application of the uncertainty principle to conditional measurements is investigated, and found to be valid for measurements on separated sub-systems. In light of this, an apparent violation of the uncertainty principle obtained by Kim and Shih in their realization of Popper's experiment (quant-ph/9905039) is explained through analogy with a simple optical system.
