Entanglement generation in autonomous thermal machines

Entanglement is a key resource for quantum information processing, and generating and maintaining entanglement is therefore a central challenge. While entanglement is fragile and generally degrades under unavoidable interactions of a system with its environment, it has been realised that dissipation may in some cases aid the generation and stabilisation of entanglement. In particular, heat gradients present in a multipartite system interacting with multiple thermal baths can induce entanglement in a steady state out of thermal equilibrium. Here, I describe thermal machines capable of generating such entanglement both in the simplest case of two qubits, and for more complicated settings of higher dimensions and multiple parties. I will touch upon possible implementations in superconducting circuits.
