Promise in Establishing Measurement of Entangled Photons Down Possibly as Short as the Zeptosecond

…Researchers from Purdue University have proposed a novel, unconventional approach to generate a special light source made up of entangled photons…

…[R]research shows promise in establishing the measurement of entangled photons down to the attosecond, and possibly even zeptosecond…

…Their work provides a road map on how to generate these entangled photons and use them to track the dynamics of electrons in molecules and materials on the incredibly short timescales of attoseconds…
