Large-scale quantum computers are hard to construct because systems easily lose their coherence through interaction with the environment. Researchers have tried avoid this problem by using geometric phase shifts in design of gates perform information processing. Experiments and simulations shown that these may be tolerant certain types faults, therefore useful for robust computation.
