Extractable work from correlations

摘要: Work and quantum correlations are two fundamental resources in thermodynamics information theory. In this work we study how to use among systems optimally store work. We analyse question for isolated ensembles, where the can be naturally divided into contributions: a local contribution from each system, global originating systems. focus on latter consider which locally thermal, thus any extractable only come correlations. compute maximum general entangled states, separable states with fixed entropy. Our results show that while entanglement gives an advantage small gain vanishes large number of
