Abstract
Mangons are newly developed as the qubits for quantum storage and information process. Here in this work, we focus on a hybrid quantum system containing two antiferromagnets, and the entanglement between magnons in the antiferromagnets could be generated through the strong coupling mediated by the same microwave mode. Moreover, we numerically simulated the process with the feasible parameters. And the influence of the system parameters, such as the magnon-photon coupling rate, the detuning, the bias magnetic field and the dissipation on the entanglement are discussed. By adjusting some of the experimental parameters, we show that two antiferromagnets can produce a large entanglement, which is a result that has not been found in other quantum systems before. Our findings may provide a potential platform for the completion of related quantum tasks in the future.
