| Abstract | We discuss the role of non-ideal measurements within the context of
measurement engines by contrasting examples of measurement engines which have
the same work output but with varying amounts of entanglement. Accounting for
the cost of resetting, correlating the engine to a pointer state and also the
cost of cooling the pointer state, we show that for a given work output,
thermally correlated engines can outperform corresponding entanglement engines.
We also show that the optimal efficiency of the thermally correlated
measurement engine is achieved with a higher temperature pointer than the
pointer temperature of the optimal entanglement engine. |
