Quantum Computing With Braids In Flatland
Braided anyons could lead to more robust quantum computing
When confined to a 2-dimensional sheet, some exotic particle-like structures known as anyons appear to entwine in ways that could lead to robust quantum computing schemes, according to research appearing in the November 1 issue of the journal Physical Review B. The physicists at Bell Laboratories who performed the research are hopeful the anyons can be induced to follow paths that twist into braids that would be much more resistant to disturbances that corrupt data and calculations in quantum computers relying on individual particles.
It's not entirely clear whether the researchers have succeeded in producing braided anyons yet, but as Kirill Shtengel (University of Caligornia, Riverside) points out in a Viewpoint article in the November 1 edition of APS Physics (physics.aps.org), the new research is a major step forward on the path to discovering strange quasiparticles that could help revolutionize computers and lead to a host of novel quantum mechanical experiments.
