摘要
We propose a scheme for quantum computation in optical lattices. The qubits are encoded in the spatial wave function of the atoms such that spin decoherence does not influence the computation. Quantum operations are steered by shaking the lattice, while qubit addressability can be provided with experimentally available techniques of changing the lattice with single-site resolution. Numerical calculations show possible fidelities above 99% with gate times on the order of milliseconds.
