Theoretical Study of Solid State Quantum Information Processing
Abstract
The objective of this research program is to provide theoretical support to the study of solid state quantum computing, with a focus on spin qubits. Our main research thrusts have been on two-spin decoherence, few-spin manipulation, and spin communication. On two-spin decoherence, we calculated phonon and nuclear spin induced dephasing, and spin-orbit and hyperfine induced relaxation. On few-spin manipulation, we studied a three-spin state transfer protocol, and explored three-spin encoding that allows full electrical control. On spin communication, we calculated spin-photon coupling in a co-planar waveguide, and studied spin relaxation of a moving but confined electron. In addition to these three main research directions, we have also studied hyperfine interaction in Si, valley properties in Si, nuclear spin dynamics in self-organized quantum dots, and electrically driven spin resonance for one and two spins.
