中文摘要we derive the generalized rate equation for the coupled quantum-dot (qd) system irradiated by a microwave field in the presence of a quantum point contact. it is shown that when a microwave field is tuned in resonance with the energy difference between the ground states of two qd's, the photon-assisted tunneling occurs and, as a result, the coupled qd system may be used as the single qubit. furthermore, we show that the oscillating current through the detector decays drastically as the dephasing rate increases, indicating clearly the influence of the dephasing effect induced by the quantum point contact used as a detecting device.
