Prepare Multiphoton Binomial State Utilizing Hybrid Circuit QED

We utilized hybrid circuit QED to prepare a multiphoton binomial state in accordance with the optimal quantum control method, and further investigated the quantum correlation dynamics of the hybrid coupling superconducting qubits. The results showed that the quantum entanglement was so weak that the duration was too short to be used as quantum information resource in the optical field of binomial state, while the geometric measure of quantum discord (GMQD) was fully adequate to the practical demand. With the increase of binomial optical field parameters M and r, the GMQD evolved more and more frequently, and collapse and revival occurred periodically. When the optical field of binomial state tended to coherent state, the collapse and revival period of the GMQD extended as the average photon number increased.
