A breakthrough in studying light might just be the ticket to the future of quantum computing. Researchers at EPFL have found a way to determine how light behaves beyond the limitations of wavelengths, opening the door to encoding quantum data in a sci-fi style holographic light pattern. The team took advantage of the quantum nature of the interaction between electrons and light to separate beams in terms energy, not space -- that let them use light pulses to encrypt info on the electron wave and map it with a speedy electron microscope.

Existing techniques for both studying light and extracting 3D info are inherently limited by the size of wavelengths. This allows a considerably higher resolution that can even include holographic movies of fast-moving objects.
