Cloning and quantum computation
arXiv:quant-ph/0002053 · doi:10.1103/PhysRevA.62.022301
Abstract
We discuss how quantum information distribution can improve the performance of some quantum computation tasks. This distribution can be naturally implemented with different types of quantum cloning procedures. We give two examples of tasks for which cloning provides some enhancement in performance, and briefly discuss possible extensions of the idea.
