Quadratic enhancement in the reliability of collective quantum engines
Noufal Jaseem, Sai Vinjanampathy, Victor Mukherjee
Abstract
In this theoretical proposal, the authors show that collective effects can be harnessed to significantly increase the signal-to-noise ratio, defined as the ratio of mean work output to the standard deviation of work output, for realistic many-body quantum thermal machines.
