Phys. Rev. B 68, 024510 (2003) [8 pages]Controllable manipulation and entanglement of macroscopic quantum states in coupled charge qubits
We present an experimentally implementable method to couple Josephson charge qubits and to generate and detect macroscopic entangled states. A large-junction superconducting quantum interference device is used in the qubit circuit for both coupling qubits and implementing the readout. Also, we explicitly show how to achieve a microwave-assisted macroscopic entanglement in the coupled-qubit system.
