Abstract:

Abstract: By virtue of the canonical quantization method, a quantization scheme for the capacitive coupling charge qubits was suggested. Considering the influence of applied magnetic field on the Josephson junction current, we therefore present a new method of controlling charge qubits and discuss the Rabi oscillation of evolution of quantum state with time and the entanglement. By using this system, entangled state can be prepared. The charge qubits can be effectively regulated with the changing applied magnetic field Φ1 and Φ2.
