This connection is fragile and usually requires cooling experiments to near absolute zero to prevent environmental disturbances from breaking the link. However, a team led by Francesco Marin at the University of Florence has achieved entanglement between a tiny levitating glass sphere and light at room temperature, publishing their findings in *Science*.<\/p>\n<p><!--more--><\/p>\n<p>The researchers used a glass sphere only 100 nanometers across, suspended in a vacuum chamber by a focused laser beam known as an optical tweezer. To manage the delicate balance required for entanglement, they combined two lasers of slightly different colors. One laser cooled and stabilized the sphere&#8217;s motion, while the second allowed that movement to become entangled with light passing between mirrors. As the sphere oscillated, information about its motion was imprinted on the light, which the team measured over many hours to reconstruct the connection pattern.<\/p>\n<p>The experiment confirmed genuine entanglement because the measured correlations crossed a specific mathematical threshold, even though the lab remained at room temperature. Crucially, this entanglement persisted in light traveling away from the mirrors. The team now aims to actively control rather than just observe this effect, potentially linking multiple levitated spheres through shared light fields. This could enable new tests of quantum mechanics at larger scales and help develop quantum networks where information moves seamlessly between moving objects and light carrying it across distances.<\/p>\n<div style=\"margin-top:2em; padding:1em; border-left:4px solid #0073aa; background:#f5f7fa;\">\n<p style=\"margin:0;\"><strong>Source:<\/strong> Phys.org &bull; October 7, 2026<\/p>\n<p style=\"margin:0.5em 0 0;\"><a href=\"https:\/\/phys.org\/news\/2026-10-levitating-glass-sphere-entangled-room.html\" target=\"_blank\" rel=\"noopener\">Read the original article at Phys.org &rarr;<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>AI-rewritten: This is a summary of an article from Phys.org, rewritten by AI (Qwen, running locally) to make it easier to read.
