Collective operations can extremely reduce work fluctuations
We consider work extraction from N copies of a quantum system. When the same work-extraction process is implemented on each copy, the relative size of fluctuations is expected to decay as $1/\sqrt{N}$ . Here, we consider protocols where the copies can be processed collectively, and show that in this...
