The Microscope That Uses Quantum Physics to Trace Atoms : Quantum microscopy
Quantum microscopy allows microscopic properties of matter and quantum particles to be measured and imaged. Various types of microscopy use quantum principles. The first microscope to do so was the scanning tunneling microscope , which paved the way for development of the photoionization microscope and the quantum entanglement microscope.
In the late 1970s, two physicists in Switzerland set out to invent a new type of microscope using quantum physics that would allow them to do something no one had ever done before: see the individual atoms in a sheet of metal.
