- The dual behaviour of light, which is demonstrated through quantum mechanics and was first proposed by Albert Einstein, was only possible to capture by scientists at École polytechnique fédérale de Lausanne (EPFL), Switzerland, due to an unorthodox imaging technique.
- The scientists generated the image with electrons, making use of EPFL’s ultrafast energy-filtered transmission electron microscope. This gave them a rare advantage over other institutions, as EPFL has one of only two microscopes in the world.
- The research could also be important for the future development of quantum-based technology. Being able to image and control quantum phenomena at the nanometer scale like this opens up a new route towards quantum computing.
