Wave-particle duality visualized in quantum movie: The video shows the build-up of a quantum interference pattern from stochastically arriving single phthalocyanine fluorescent-dye molecules after they traversed an ultra-thin nanograting. These represent the most massive molecules in quantum far-field diffraction so far.
The researchers used a spatially resolving fluorescence microscope whose sensitivity is so high that each molecule can be imaged and located individually with an accuracy of about 10 nanometers.
