Center for Quantum Device Technology

The main objective of our program has been the exploration of coherent quantum mechanical processes in novel solid-state semiconductor information processing devices, with components of atomic dimensions: quantum computers, spintronic devices, and nanometer-scale computer logic gates.

The achievements to date include new modeling tools for evaluating initial decoherence and transport associated with quantum measurement, spin polarization control, and quantum computer design, in semiconductor device structures.

Our program has involved an interdisciplinary team, from Physics and Electrical Engineering to Computer Science and Mathematics, with extensive collaborations with leading experimental groups and with Los Alamos National Laboratory.

The educational impact includes training undergraduate students, graduate students, postdoctoral researchers, and the development of three new courses to introduce quantum nanotechnology concepts to undergraduate and graduate students.

Our outreach program has included sponsoring conference events, an international Quantum Device Technology workshop series, and numerous lectures and presentations.
