Sean Barrett gained a BA and MSc in Physics at Cambridge University in 1999. Between 1999 and 2002 he was a post graduate student in the Physics Department at Cambridge University. He joined HP Labs in January 2003.

Although Sean is primarily interested in theoretical physics, much of his inspiration is drawn from close collaboration with experimental physicists. During his post graduate studies he contributed to a practical proposal for solid state quantum computation using sodium impurities in silicon, which is presently being pursued by researchers in the Semiconductor Physics Group at Cambridge. He has also engaged in fruitful collaborations with scientists at the Centre for Quantum Computer Technology in Australia.
