We show that the bipartite perfect matching problem is in quasi-NC2. That is, it has uniform circuits of quasi-polynomial sizenO(logn), andO(log2n) depth. Previously, only an exponential upper bound was known on the size of such circuits with poly-logarithmic depth.We obtain our result by an almost complete derandomization of the famous Isolation Lemma when applied to yield an efficient randomized parallel algorithm for the bipartite perfect matching problem.
