Nonlinear Dynamics and Quantum Computers

Abstract:

John David Crawford was an expert in dynamical systems and bifurcation theory, which is the study of systems that are subject to strong driving. This talk will discuss why this area of research is important for quantum computation.  In particular, it will be shown how concepts from nonlinear dynamics proved to be critical in the development and improvement of qubits, the fundamental building blocks of quantum computers, using quantum dots in silicon/silicon-germanium heterostructures.
