Incorrect results from Kominis's approach due to quantum jump misinterpretation

Proper quantum jump treatment aligns with traditional master equations

Provides clarification on quantum measurement theory application in spin chemistry

Abstract

Recently, spin-selective radical pair reactions have been studied using concepts from quantum measurement theory. In this Article, we show that the approach taken by Kominis (Physical Review E, 83, 2011, 056118) leads to erroneous results due to a problematic treatment of quantum jumps. Correct consideration of quantum jumps leads to either the traditional master equation or the Jones-Hore master equation.
