The turbulent atmosphere is better than an equivalent glass fiber when it comes to preserving quantum information in long-distance light signals, according to a new analysis. For brief moments, light can propagate relatively undisturbed.
A theoretical analysis of recent experiments suggests that a key feature of a topological quantum computer—the unusual statistics of quasiparticles in the quantum Hall effect—may finally have been observed.
