The accuracy of Jarzynski's measurement scheme was known to be determined by the variance of exponential work, denoted as ${\\rm var}\\left(e^{-\\beta W}\\right)$. However, it was recently found that ${\\rm var}\\left(e^{-\\beta W}\\right)$ can systematically diverge in both classical and quantum cases.
