Buffer for Light: A Step Toward the Quantum Internet ⚡ экспресс
Original: "A Universal All-Fiber Quantum Buffer for the Telecom Band"
A fiber optic buffer with an 18-microsecond delay holds light while barely disturbing quantum information, to synchronize signals for the internet of the future.

Light is hard to catch and hold. Scientists have created an optical buffer the size of a fiber optic spool that 'freezes' photons for 18 microseconds, as if light gets stuck in a mirror maze. It works at room temperature and loses almost no signal. This will help build the quantum internet.
🎯 Almost all intercontinental communication operates in the 1530–1565 nm range — the only one where fiber optic glass is so transparent that a signal can travel hundreds of kilometers without amplification.
🎬 The dream of a quantum internet sometimes evokes the fictional 'ansible' — a device for instant communication across galaxies, though in reality even it doesn't violate the speed of light limit.
