Entanglement in a quantum heat engine

Sammanfattning: In 2015 Jonatan Bohr Brask et al. showed that steady-state entanglement could be generated in two interacting qubits incoherently coupled to thermal baths of different temperatures [1]. This thesis is an attempt to re-evaluate their findings with the hope that a slightly different approach and system can help further our understanding of this not yet well understood phenomena. A Lindblad master equation approach is taken to study a two-qubit thermal machine interacting with bosonic thermal reservoirs. It is found that the steady-state entanglement behaves similarly using the Lindblad approach, the main difference being that a larger amount of entanglement can be generated than initially found in Ref. [1].
