The heat price of precision
In plain wordsPlaying a quantum game more precisely can cost heat: if the devices reset separately before communicating again, some fixed finite games need work growing like a multiple of log(1/ε) at error ε, but reuniting the quantum systems before the reset keeps the work bounded.
The result
As the paper states it, in briefFor games whose usable-entanglement demand diverges, resetting locally before communicating forces divergent work, while bringing the systems back together before reset keeps the operating work bounded.
