TITLE:		Room-temperature Quantum Computing with Diamond Defects

SPEAKER:	NORMAN YAO  (Harvard University)


ABSTRACT:

The realization of a scalable quantum information processor has emerged 
over the past decade as one of the central challenges at the interface of 
fundamental science and engineering.  In this talk, I will describe an 
architecture for a scalable, solid-state quantum information processor 
capable of operating at room temperature.  I will begin with a review of 
quantum computation that focuses on the interplay between speedup, 
decoherence and fault-tolerance.  I will then describe our specific 
approach, which is based upon recent experimental advances involving 
Nitrogen-Vacancy color centers in diamond.  In particular, we demonstrate 
that the multiple challenges associated with operation at ambient 
temperature, individual addressing at the nanoscale, strong qubit 
coupling, robustness against disorder and low decoherence rates can be 
simultaneously achieved under realistic, experimentally relevant 
conditions.  The architecture uses a novel approach to spin-chain based 
quantum information transfer and includes a hierarchy of control at 
successive length scales.
