The design of a quantum Benes switch

In this paper, we propose a novel framework for building a NtimesN quantum Benes switch that can route quantum packets without blocking. Previous studies about quantum systems have discussed many switching algorithms including merge sorting (Cheng and Wang, 2006) or self-routing Banyan switch (Shukla et al., 2005) etc. We build a newly quantum parallel routing scheme that achieves internally conflict free and real-time path permutations by using the quantum logic circuit modules.
