The Pattern Broke. The Number Survived.
A topological invariant carried by entangled light remained intact after turbulence destroyed the beam's recognizable shape.
Summary
A topological invariant carried by entangled light remained intact after turbulence destroyed the beam's recognizable shape.
A University of the Witwatersrand team sent structured quantum light through strong atmospheric turbulence and found that the visible spatial pattern and conventional entanglement signal degraded while a topological number embedded in the state remained recoverable. The Physical Review Letters experiment suggests a more resilient way to encode high-dimensional quantum information, but it is a laboratory result rather than an operational bad-weather communications network.
Why it matters
