Abstract
The work extractable from correlated bipartite quantum systems can be used to
distinguish entanglement from classical correlation. A natural question is now
whether it can be generalised to multipartite systems. In this paper, we devise
a protocol to distinguish the GHZ, the W, and separable states in terms of the
thermodynamically extractable work under local operations and classical
communication, and compare the results with those obtained from Mermin's
inequalities.
