Abstract

Several authors have described the basic requirements essential to building a scalable quantum computer. Because many physical implementation schemes for quantum computing rely on nearest neighbor interactions, there is a hidden quantum communication overhead to connect distant memory nodes of the computer. In this paper we provide a solution to this problem which together with the key building blocks provides a pathway to building a scalable quantum architecture using nonlocal interactions. Our solution involves the concept of a quantum bus that acts as a refreshable entanglement resource to connect distant memory nodes. In some ways the concepts described here along with the initial requirements provide a broad architectural concept for quantum computers in a manner analogous to the von Neumann architecture for classical computers.
