- Abstract: We investigate entanglement mediated by DC current induced nonreciprocal
graphene plasmon polaritons. Nonreciprocal systems are ideal for the
enhancement, control, and preservation of entanglement due to the potential for
unidirectional beam-like wave propagation, i.e., efficiently transporting
photons from one emitter to another. Using a quantum master equation and
three-dimensional Green's function analysis, we investigate a system consisting
of two two-level emitters dominantly interacting via electric current induced
nonreciprocal plasmonic modes of a graphene waveguide. We use concurrence as a
measure of entanglement. We show that nonreciprocal graphene plasmon polaritons
are a promising candidate to generate and mediate concurrence, where it is
shown that there is good enhancement and control of entanglement over vacuum,
which is beneficial for the broad applications of entanglement as a quantum
resource. We believe our findings contribute to the development of quantum
devices, enabling efficient and tunable entanglement between two-level systems,
which is a central goal in quantum technologies.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

Enhanced interaction between two two-level emitters (e.g., atoms) by nonreciprocal photonic media can be of benefit to broad areas.
We show that breaking electromagnetic reciprocity makes it possible for the cooperative decay rate to exceed the spontaneous decay rate.
We then show that breaking reciprocity in such a system via driving a DC current through the plasmonic material can drastically increase the probability of photon emission from one emitter to another.
