Abstract

Quantum dots can be utilized as computational elements.  However, the
quantum dot is not a direct replacement for the transistor.  New computing
architectures are required.  As a result, the algorithms that utilize
these architectures must be transformed for efficient implementation.
Additionally, these architectures are required to be fault tolerant
to manufacturing variations and defects.  Therefore, we are developing
quantum dot circuits that implement signal processing algorithms, and
we are developing software tools that allow us to perform Monte Carlo
simulations and statistical analyses of quantum dot circuits.

Biography

Mr. Duane Armstrong is a Senior Electronics Engineer at NASA Langley
Research Center.  During his 17-year tenure with Langley, Mr. Armstrong
has designed state-of-the-art analog and digital electronics for
scientific instruments that have flown on high-performance aircraft,
the space shuttle, and satellites.  He has pursued research interests in
the areas of radiation-hardened electronics, mixed-signal ASIC design
and tunneling electron sensors.  His current research focuses on the
development of quantum dot sensors and quantum dot circuits for both
classical and quantum computing.
