Disclosed herein are a force realization apparatus using a superconducting flux quantum, which is capable of generating force proportional to a flux quantum number by including a micron-sized superconducting annulus or superconducting quantum interference device in an ultra-sensitive cantilever, and a force measurer using the same. The quantum-based force realization apparatus includes: superconducting quantum trap means having a magnetic moment proportional to a flux quantum number; an ultra-sensitive cantilever which mounts therein the superconducting quantum trap means, has elasticity and is displaced by force generated by the superconducting quantum trap means located in a magnetic field gradient; and a magnetic field generator which applies a magnetic field to the superconducting quantum trap means.
