Seminar: Artificial atoms in computing: theory, applications, and challenges

Seminar| Institute of Mathematical Sciences

Abstract: A promising route to quantum computing is the creation of electron quantum dots on a superconducting substrate. If such “valence” electrons are critically isolated, they behave as critically coherent multiplets—analagous to natural atoms together in a superposition of ionic and covalent bonds. Degrees of freedom are carried by electron spins, and quantum spintronic information processing can occur when the dots are in a critically isolated regime. But sufficient control over the device’s state is needed to achieve critical isolation, and measurement and control problems must be solved for large scale practical quantum computing to occur.
