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.
