There is a important paper in today's journal Nature on error correction that would be needed to make Quantum Computers practical. Although they still can't protect individual Qubits they could protect the entanglement of 3 or more particles (the Greenberger–Horne–Zeilinger state) and they could use quantum methods to correct errors in classical information.
