Provided is a system, an information processing method, and a non-transitory storage medium that hardly cause improper operations when a plurality of quantum processors is connected to configure a logical quantum bit. A system includes a plurality of quantum processors, each including a plurality of physical quantum bits, the system performing processing such that the quantum processors of a first group from among the plurality of quantum processors configure at least one logical quantum bit including the physical quantum bits; the quantum processors of the first group perform error checking on the logical quantum bit; the quantum processors of a second group from among the plurality of quantum processors configure at least one logical quantum bit including the physical quantum bits; if an error is detected at least in error checking on the quantum processors of the first group, the system swaps a quantum state of the quantum processors of the first group with a quantum state of the quantum processors of the second group, and the system performs error checking on the logical quantum bit.

System of quantum processors, information processing method, and non-transitory storage medium thereof

A search device, a search method, and a search program for causing a quantum computer to search for angles of joints of a robot such as a robot arm at which the posture of the robot satisfies a predetermined condition by using a quantum algorithm are provided. The search device includes a specifying unit that specifies a function for identifying whether or not a posture of a robot satisfies a predetermined condition, a setting unit that applies a unitary transformation formed based on the function to a plurality of qubits corresponding to an angle of a joint of the robot a number of times according to the number of the plurality of qubits and sets a quantum computer so as to search for a state of the plurality of qubits corresponding to the angle satisfying the predetermined condition according to a quantum algorithm, and a calculation unit that calculates the angle corresponding to a measurement value of the plurality of qubits.
