1. A microscope using quantum-mechanically entangled photons comprising:
a photon source which sequentially generates sets of quantum-mechanically entangled photons including at least two photons;
a splitter splitting the quantum-mechanically entangled photons into individual photons traveling in different directions;
lenses which focus the individual photons, respectively;
actuators which vary relative distances between focal positions of the respective lenses on which the individual photons are
focused and specimens having a same structure with a displacement, respectively, the specimens being arranged near the focal
positions of the respective lenses;
detectors detecting a photon transmitted through or scattered by the specimens, respectively; and
a counter counting coincidence detections of the photons with the detectors depending on the varied relative distances.
