Architectural Issues in Scalable Quantum Computing

Computing with quantum states has become an increasingly intriguing 
reality. Prototype quantum computers of 5 to 7 bits have begun to appear 
using molecules in solution and photon traps. For true scalability and 
to exploit our tremendous historical investment in silicon, however, 
solid-state silicon quantum implementations are needed.

This talk begins with some background in quantum computing. I then focus 
on two fundamental issues in future architectures. First, the movement 
of quantum data on silicon. Second, reducing the overhead of error 
correction to cope with environmental noise.

We propose a novel approach to low-latency, reliable communication 
through a "quantum wire" architecture that uses teleportation of 
error-coded quantum bits. I discuss the architectural building blocks 
for quantum wires and quantum computation in general. I further discuss 
quantum error correction codes and how to reduce their overhead. I 
conclude with some work that exploits both quantum wires and different 
error correction codes to form a quantum memory hierarchy.

This is joint work with Mark Oskin, Ike Chuang, Dean Copsey, and John 
Kubiatowicz and conducted as part of the Quantum Architecture Research 
Center funded by the DARPA Quantum Information Science and Technology 
Program.

Fred Chong is an Associate Professor and Chancellor's Fellow in the 
Department of Computer Science at the University of California at Davis. 
He received his Ph.D. in 1996 from MIT and is a recipient of the 
National Science Foundation's CAREER award. His current research focuses 
on architectures and applications for novel computing technologies.
