Abstract:
We will introduce the problem of scalable error characterization, and the use of the fidelity decay as a tool to characterize these errors efficiently. We will concentrate then on our scheme to analyze spatial correlations (also termed range or locality, and relevant to evaluate fault-tolerance) and its experimental implementation in liquid state NMR QIP (quant-ph/0805.4825). We will discuss the practical aspects regarding scalability, accuracy and implementation errors.
