Quantum Information

I'm interested in understanding how the structure of molecules or materials affects their behavior. To understand this, I develop methods to model these materials properties more accurately, and apply them to materials that are interesting to me and important to the nation.

I’m currently interested in quantum computing and in arriving at a better understanding of the materials-related issues involved.  I’m currently working with a group of researchers at Sandia to answer some of these fundamental questions.  We’re focusing on solid-state qubits in Silicon, using either electrostatically gated quantum dots, or implanted donor devices.  We’re interested in understanding the requirements to make qubits using such devices, and, given such qubits, what their operations and errors will look like.

We have recently developed the QCAD (quantum dot computer aided design) program, which is a finite element code built atop the Trilinos rapid application development library Albany. The code enables sophisticated 3D semiconductor quantum structures to be modeled to determine how structural changes in the devices lead to different quantum device properties. The code also uses the Dakota optimization library to determine optimal voltages to obtain few-electron dot behavior.
