Abstract
We show that a hybrid quantum device consisting of three ensembles of nitrogen-vacancy (NV) centers whose spins are collectively coupled to a superconducting coplanar waveguide resonator enables the generation of controllable macroscopic tripartite entangled states. At the instants of time when the waveguide resonator is completely depleted of photons and is thus disentangled from the NV-center ensembles, macroscopic Greenberger–Horne–Zeilinger-type states are generated in NV-diamond memories.
