Measuring entanglement in a quantum heat engine

We study how entanglement in a quantum heat engine can impact its non-equilibrium thermodynamics. For this purpose we consider a network of qubits whose state can be fully controlled by entangling gates and rotation gates. We weakly couple the network to a number of heat reservoirs, each kept at a different temperature. Heat flows between the reservoirs run via the network and are studied for different entangled states of this network. Some entangled states reveal interesting properties in the heat flow thereby furthering our understanding of the quantum nature of such thermodynamical systems.
