Robust dynamical decoupling: feedback-free error correction
Kaveh Khodjasteh, Daniel A. Lidar · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2005
Dynamical decoupling is a feed-back free scheme for quantum error correction against noise and decoherence errors. An efficiency analysis of dynamical decoupling is performed. Furthermore we provide the basic concepts of dynamical decoupling and quantum error correction codes, and give an example of a hybrid protection scheme. Some interesting extensions of dynamical decoupling are discussed at the end.
