contents Based on the physical process of two-atom simultaneous excitation by single photon, we proposed a frequency dividing scheme in superconducting quantum circuit. The frequency division for a microwave photon consists of two quantum processes: firstly, two qubits share the energy of single photon in high-frequency resonator through the three-body interaction (two qubits and one photon); secondly, part energies of excited state qubits are transferred to corresponding low frequency resonators through two-body interactions (one qubit and one photon). By changing the parameters of pumping pulses, controllable output pulses can be realized through the superconducting frequency divider. The microwave and pulse signals created by the superconducting frequency divider can be used to pump or readout the superconducting qubits, which can greatly reduce the occupation amount of high-frequency cables in dilution refrigerator during the measurement of large scale superconducting quantum chip.
