Cover Story: Quantum energy coherences represent a thermodynamic resource, which can be exploited to extract energy from a thermal reservoir and deliver that energy as work. There exists a closely analogous classical thermodynamic resource, namely, energy–shell inhomogeneities in the phase space distribution of a system’s initial state. The amount of work that can be obtained from quantum coherences can be shown to be equal to the amount that can be obtained from classical inhomogeneities in the semiclassical limit. Thus, coherences do not provide a unique thermodynamic advantage of quantum systems over classical systems in situations where a well-defined semiclassical correspondence exists. View this paper

Most previous studies on multi-agent systems aim to coordinate agents to achieve a common goal, but the lack of scalability and transferability prevents them from being applied to large-scale multi-agent tasks. To deal with these limitations, we prop...
