A Theory for Valiant's Matchcircuits (Extended Abstract)

Abstract

The computational function of a matchgate is represented by its
character matrix. In this article, we show that all nonsingular
character matrices are closed under matrix inverse operation, so
that for every $k$, the nonsingular character matrices of $k$-bit
matchgates form a group, extending the recent work of Cai and
Choudhary (2006) of the same result for the case of $k=2$, and that
the single and the two-bit matchgates are universal for
matchcircuits, answering a question of Valiant (2002).
