TY - JOUR T1 - A Quantum Computer Architecture using Nonlocal Interactions JF - Physical Review A Y1 - 2003 A1 - Gavin K. Brennen A1 - Daegene Song A1 - Carl J. Williams AB - Several authors have described the basic requirements essential to build 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 nodes of the computer. In this paper we propose a physical solution to this problem which, together with the key building blocks, provides a pathway to 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 providing an architectural concept for quantum computers analogous to the von Neumann architecture for classical computers.
