In this paper we propose a new protocol for quantum teleportation between two LC resonators in Alice’s and Bob’s lab via superconducting qubits. The coupling of superconducting qubits with each other and with LC resonators are tunable by applying the external magnetic fields. We use this model to generate entanglement between superconducting qubits and teleport the unknown state of LC resonator in Alice’s to Bob’s lab. To implement teleportation, the result of Alice’s Bell state measurement is classically informed to Bob. Finally, the unknown state of LC resonator in Alice’s lab is teleported to the state of LC resonator in Bob’s lab by applying a phase gate and a proper unitary rotating operator on the state of LC resonator in Bob’s lab. It is observed that the target state is teleported to the LC resonator in Bob’s lab with maximum possible fidelity.
