Multi-party Entanglement Generation Through Superconducting Circuits

In this article multipartite entanglement generation schemes are suggested using Circuit Quantum Electrodynamics (Circuit-QED). These proposed setups are achieved by building an interactive connection among many charge qubits, which act as an artificial atom as well as coupler. By initializing these charge qubits in a circuit, one can obtain the multiparty entanglement among these qubits. Further, the charge qubits used for coupling the circuit are traced out. These maximally entangled states are experimentally feasible and can exhibit good fidelity and can further be utilized for quantum information processing tasks.
