Comment on "Unity-Efficiency Parametric Down-Conversion via Amplitude Amplification" [arXiv:1603.06857]
M.K. Olsen
TL;DR
This paper critiques a previous proposal for achieving unity efficiency in spontaneous parametric down-conversion, identifying and correcting errors in the original probability calculations.
Contribution
It provides a critical correction to the probability calculations in the original work, clarifying the feasibility of unity efficiency in SPDC.
Findings
Original probability table contained errors.
Corrected probabilities challenge the feasibility of unity efficiency.
Highlights importance of accurate probability analysis in quantum optics.
Abstract
There is a serious flaw in the proposal [arXiv:1603.06857] for the achievement of unity efficiency in SPDC. This is a replacement due to mistakes in the table of probabilities. Numbers have been corrected.
