Résumé

We consider a metric $D$ describing the difference between real (noisy) and ideal processes that is based on the operator norm of the maximum deviation between the final real and ideal states of a quantum system. We discuss the properties as well as geometric and experimental interpretations of the metric.

Détail

Keywords: decoherence, quantum channels, decoherence metric, operator norm, noise level estimation.
