The theory of CWS codes is the most general theory of QECCs to date, as it encompasses graph codes, of which the four-qubit graph code we have realized is the simplest instance, and non-additive ...

This paper presents a non-technical exposition of graph theory (more particularly, the theory of directed graphs or digraphs), followed by a survey of the literature on applications of graph theory in ...

By carefully constructing a multidimensional and well-connected graph, a team of researchers has finally created a long-sought locally testable code that can immediately betray whether it’s been… ...
