Quantum information processing in bosonic lattices
arXiv:quant-ph/0204118 · doi:10.1103/PhysRevA.66.050301
Abstract
We consider a class of models of self-interacting bosons hopping on a lattice. We show that properly tailored space-temporal coherent control of the single-body coupling parameters allows for universal quantum computation in a given sector of the global Fock space. This general strategy for encoded universality in bosonic systems has in principle several candidates for physical implementation.
