Abstract
We investigate the possibility of correcting errors occurring on a multipartite system through a feedback mechanism that acquires information through partial access to the environment. A partial control scheme of this type might be useful in dealing with correlated errors. In fact, in such a case, it could be enough to gather local information to decide what kind of global recovery to perform. Then, we apply this scheme to the depolarizing and correlated errors and quantify its performance by means of entanglement fidelity.This publication has 14 references indexed in Scilit:
