Hybrid quantum networks of stationary and ``flying'' qubits are essential for distributed quantum information processing. In superconducting quantum computation, two-qubit gates are currently realized by the interaction between neighboring qubits. The authors propose a gate comprising a superconducting ``atom'' and a microwave photon, in which gate operation is completed d\phantom\rule00exe\phantom\rule00ext\phantom\rule00exe\phantom\rule00exr\phantom\rule00exm\phantom\rule00exi\phantom\rule00exn\phantom\rule00exi\phantom\rule00exs\phantom\rule00ext\phantom\rule00exi\phantom\rule00exc\phantom\rule00exa\phantom\rule00exl\phantom\rule00exl\phantom\rule00exy (not probabilistically) upon reflection of the photon. This gate's type can be continuously varied i\phantom\rule00exn s\phantom\rule00exi\phantom\rule00ext\phantom\rule00exu, enabling r\phantom\rule00exe\phantom\rule00exm\phantom\rule00exo\phantom\rule00ext\phantom\rule00exe entanglement of many ``atoms'' via a single photon, or creation of a quantum domino effect.
