New optical tornado technology could transform quantum communication

Scientists have created tiny optical tornadoes - swirling beams of light that twist like miniature whirlwinds - using a surprisingly simple setup based on liquid crystals. Instead of relying on complex nanotechnology, the team used self-organizing structures called torons to trap and manipulate light, causing it to spiral and rotate in intricate ways. Even more impressively, they achieved this effect in lights most stable, lowest-energy state, making it far easier to generate laser-like beams wi...
