Test generation and fault localization for quantum circuits

Abstract

It is believed that quantum computing will begin to have a practical impact in industry around year 2010. We propose an approach to test generation and fault localization for a wide category of fault models. While in general we follow the methods used in test of standard circuits, there are two significant differences: (2) we use both deterministic and probabilistic tests to detect faults, (2) we use special measurement gates to determine the internal states. A fault table is created that includes probabilistic information. "Probabilistic set covering" and "probabilistic adaptive trees" that generalize those known in standard circuits, are next used.
