To provide a quantum motor capable of reliably carrying out rotation. A quantum motor (10) includes a rotor (60) containing a functional material of which quantum characteristic is externally controllable, an N pole permanent magnet (20) and an S pole permanent magnet (30) applying magnetic field to the rotor (60), and a light source (90) varying the quantum characteristic of the rotor (60). The light source (90) varies the quantum characteristic of the rotor (60), so that rotation force is generated in the rotor (60) and the rotor (60) rotates.
