Manipulation and entanglement of capacitive coupled charge qubits
By virtue of the Dirac canonical quantization method, a quantization scheme for the capacitive coupled charge qubits was suggested. Considering the influence of applied magnetic field on the Josephson junction current, a new method of controlling charge qubits was presented and the Rabi oscillation of evolution of quantum state with time and the entanglement was discussed. By using this system, entangled state can be prepared. The charge qubits can be effectively manipulated with the changing applied magnetic field Φ1 and Φ2.
