One-of-a-kind microscope enables breakthrough in quantum science

Posted by in categories: computing, quantum physics, science

Technion Professor Ido Kaminer and his team have made a dramatic breakthrough in the field of quantum science: a quantum microscope that records the flow of light, enabling the direct observation of light trapped inside a photonic crystal.

Their research, “Coherent Interaction Between Free Electrons and a Photonic Cavity,” was published in Nature. All the experiments were performed using a unique ultrafast transmission electron microscope at the Technion-Israel Institute of Technology. The microscope is the latest and most versatile of a handful that exist in the scientific world.

“We have developed an electron microscope that produces, what is in many respects, the best near- field optical microscopy in the world. Using our microscope, we can change the color and angle of light that illuminates any sample of nano materials and map their interactions with electrons, as we demonstrated with photonic crystals,” explained Prof. Kaminer. “This is the first time we can actually see the dynamics of light while it is trapped in nano materials, rather than relying on ,” added Dr. Kangpeng Wang, a postdoc in the group and first author on the paper.
