Turbulence Modelling Reveals Interference in Quantum Free-Space Optical Links

Quantum Zeitgeist Archived Apr 11, 2026 ✓ Full text saved

Can quantum information truly be transmitted through turbulent air without relying on simplified assumptions about the channel itself? A new model derives the Quantum MIMO channel directly from wave-optical propagation, explicitly accounting for atmospheric turbulence and finite detection apertures, a departure from previous methods. This approach reduces the complex channel to a standard, correlated n-qubit erasure channel, opening new avenues for optimising quantum communication systems.
