Abstract
We propose an effective scheme for realizing a Jaynes-Cummings (J-C) model with the collective nitrogen-vacancy center ensembles (NVE) bosonic modes in a hybrid system. Specifically, the controllable transmon qubit can alternatively interact with one of the two NVEs, which results in the production of $N$ particle entangled states. Arbitrary $N$ particle entangled states, NOON states, N-dimensional entangled states and entangled coherent states are demonstrated. Our method is insensitive to cavity decay and spontaneous emission of the NV center since no cavity photons or excited levels of the NV center are populated during the whole process. Realistic imperfections and decoherence effects are analyzed via numerical simulation. The idea provides a scalable way to realize NVEs-circuit cavity quantum information processing with current technology.
