Constant-Space Zero-Knowledge Proofs Systems with One-Way Quantum Verifiers -- Preliminary Report --
Marcos Villagra, Tomoyuki Yamakami (Univ. of Fukui) COMP2013-36
Abstract (in Japanese) (See Japanese page) 
(in English) We discuss the notion of quantum zero-knowledge proof systems whose memory-limited verifiers
receive a stream of classical input symbols. We model such verifiers as one-way quantum finite automata working on input strings. Our proof systems require the recognition zero-knowledge property of Dwork and Stockmeyer [JACM, 1992]. Here, we report a preliminary set of fundamental properties of such proof systems. With the use of one-way quantum finite automata as verifiers, all proofs of the properties do not rely on any unproven complexity-theoretical assumptions.
