| Abstract: | A small Josephson junction(a artificial atom) coupled to a resonant cavity is expounded,we show the Hamiltonian of the junction-cavity system.Then,under some conditions,we obtain the simplified form of the Hamiltonian.Finally,we propose a quantum computing scheme of two artificial atoms coupled to a single-mode resonant cavity,which performs a control-NOT gate. |
