Query: Waveguide-QED-Based Photonic Quantum Computation   We propose a new scheme for quantum computation using flying
qubits--propagating photons in a one-dimensional waveguide--interacting with
matter qubits. Photon-photon interactions are mediated by the coupling to a
three- or four-level system, based on which photon-photon \pi-phase gates
(Controlled-NOT) can be implemented for universal quantum computation. We show
that high gate fidelity is possible given recent dramatic experimental progress
in superconducting circuits and photonic-crystal waveguides. The proposed
system can be an important building block for future on-chip quantum networks.
