Decoherence and Noise in Spin-based Solid State Quantum Computers. Approximation-Free Numerical Simulations
Abstract
This project has developed and used advanced high-precision numerical techniques to accurately assess the details of the decoherence process governing the dynamics of qubits interacting with spin environments. Analytical results and coherent state numerical techniques (similar to those pioneered in quantum optics by R. Glauber) have also been developed and applied. Most recently, specific strategies for quantum control have been investigated for realistic systems in order to extend the coherence times for spin-based quantum computing implementations. Many of the investigations were motivated by recent laboratory results and were studied and driven via interactions with experimental groups supported by the QC program. 14 publications were produced, 18 invited talks given, and 4 postdocs were trained.
