dc.description.abstract
We demonstrate that entanglement of two macroscopic nanoelectromechanical
resonators ‒ coupled to each other via a common detector, a tunnel junction ‒
can be generated by running a current through the device. We introduce a setup
that overcomes generic limitations of proposals suggesting to entangle systems
via a shared bath. At the heart of the proposal is an Andreev entangler setup,
representing an experimentally feasible way of entangling two nanomechanical
oscillators. Instead of relying on the coherence of a (fermionic) bath, in the
Andreev entangler setup, a split Cooper pair that coherently tunnels to each
oscillator mediates their coupling and thereby induces entanglement between
them. Since entanglement is in each instance generated by Markovian and non-
Markovian noisy open system dynamics in an out-of-equilibrium situation, we
argue that the present scheme also opens up perspectives to observe
dissipation-driven entanglement in a condensed-matter system.
