Fault-tolerant quantum computation: Attraction of all-optical control

(Science China Press) Quantum computation is one of the ways to break the bottle-neck of modern IC. Holonomic quantum computation is a quantum computation strategy that promises some built-in noise-resilience features. Now, researchers in Guangzhou and Hefei provide a fault-tolerant quantum computation scheme based on electronic spins in diamond with all-optical manipulation. This scheme opens the possibility for robust quantum computation with current technology.
