Magnet-Free Structured Light Control Could Advance Quantum Communications
Researchers at Vilnius University have developed a theoretical method that uses light to pre-program atoms to reshape and control complex structured laser beams without requiring external magnetic fields. The model shows that a prepared atomic gas can modify both the spatial structure and polarization of optical vector vortices, creating a feedback process in which light shapes the atoms and the atoms in turn reshape the light. This all-optical approach could provide a more scalable way to manipulate [...]
