Coherent control of quantum information
… incoherence can be difficult to separate from decoherence. By studying the fidelity decay under the cyclic entangling map, the effects of incoherence are easily distinguished from decoherence in experimental data. Decoherence free subspaces (DFSs) provide some of the most efficient schemes of …

Engineering coherent control of quantum information in spin systems
… power of QIP is compromised in the presence of decoherence. One method of protecting information from collective decoherence is to limit the quantum states to those respecting the symmetry of the noise. These decoherence-free subspaces (DFS) encode one logical quantum bit (qubit) within multiple …

Quantum Information Processing using the Power-of-SWAP
… methods to find the relevant invariant subspaces and associated vector-states. Some interesting patterns of states are found including onedimensional invariant subspaces spanned by W-states and the Hamming-weight preserving symmetry of the vectors spanning the various invariant …
