What this means

This document is a news article from the University of the Witwatersrand (Wits University) dated 29 July 2026. It reports a research breakthrough showing that quantum information encoded in the topology of “twisted” light can remain intact even after passing through strong atmospheric turbulence and storm-like conditions, despite the physical light patterns becoming warped and fragile. The article says the results were published in Physical Review Letters and suggests the approach could enable more secure, resilient global communication networks and ultra-resilient quantum computers.
