Zusammenfassung:	A flying qubit is proposed that uses an elementary excitation in superconducting nanocircuits including Josephson transmission lines. Our proposed qubit can resolve an existing qubit-manipulation problem that is unavoidable in solid-state based quantum computers, and has the potential for integrating computation and communication using its flying nature. A concrete example is provided of quantum logic gates using our proposed qubit.
