PROBLEM TO BE SOLVED: To utilize strong coupling of a resonator mode with a transition of a great transition dipole moment and wide homogenous width for a quantum gate. SOLUTION: This method includes causing a common-resonator mode resonating with a transition between ¾2>i and ¾3>i that are coupled, as states, to each other by a transition having a homogenous width greater than an energy difference between ¾0>i and ¾1>i, ¾0>i and ¾1>i representing quantum bits of a physical system i in a resonator; transferring states of quantum bits represented by ¾0>k and ¾1>k to ¾4>k and ¾5>k having a mutual energy difference greater than a homogeneous width and each having an energy diffrence greater than that of either of ¾2>i and ¾3>i by a homogeneous width or more, respectively, when a quantum-bit-gate operation using the common-resonator mode is executed in m physical systems k; executing adiabatic passage between the physical systems using light that resonates with a transition between ¾3>k and ¾4>k and a transition between ¾3>k and ¾5>k; executing the quantum-bit-gate operation between the m quantum bits; and transferring, to ¾0>k and ¾1>k, the states represented by ¾4>k and ¾5>k, respectively.
