Abstract

The limits to miniaturization of electronic devices are reached with sizes where quantum mechanics rules over the dynamics of the system. Because of this, enormous efforts are being made in search of new technologies to store and process information that can efficiently replace classic electronics. The proposal for quantum systems for carrying out computation represents an attempt to create a new generation of information processors (Nielsen & Chuang, 2003). The major advantage of quantum computation is that it can resolve numeric problems that cannot be resolved by classical computation. However, there remains the unresolved problem of the coherence of the proposed systems. Some significant advances have been made in addressing these problems using dislocated qubits with global control protocols (Fitzsimons et al., 2007), with small molecular systems.
