Underlying Information Technology Tailored Quantum Error Correction

Abstract

MAJOR ACCOMPLISHMENTS: * Developed a theory of fault-tolerant quantum dynamical decoupling (DD) * Showed how to construct optimized DD procedures from empirical data * Gave conditions for optimal decoherence free subspaces (DFS) * Developed an optimal algorithm for quantum process tomography, with quadratic speedup over all previously known such algorithms (no connection to Grover speedup) * Developed a completely positive post-Markovian quantum master equation * Developed a range of hybrid quantum error correction, DFS, and DD protocols, tailored to various quantum computing.
