"Building a quantum computer using silicon quantum dots" :
It has been shown theoretically that by exploiting the nature of quantum physics, quantum computers can solve certain computational problems much more efficiently than classical computers can. To build a quantum computer that is large enough to provide a significant advantage, fundamental physics advances are required. This talk will discuss the challenges involved in building a large-scale quantum computer as well as progress that we have made in developing a quantum computer using quantum dots in silicon/silicon-germanium heterostructures.
