  Converting quantum information from stationary qubits to traveling photons
enables both fast qubit initialization and efficient generation of flying
qubits for redistribution of quantum information. This conversion can be
performed using cavity sideband transitions. In the fluxonium, however, direct
cavity sideband transitions are forbidden due to parity symmetry. Here we
circumvent this parity selection rule by using a three-wave mixing element to
couple the fluxonium to a resonator. We experimentally demonstrate a scheme for
interfacing the fluxonium with traveling photons through microwave-induced
parametric conversion. We perform fast reset on the fluxonium qubit,
initializing it with > 95% ground state population. We then implement
controlled release and temporal shaping of a flying photon, useful for quantum
state transfer and remote entanglement. The simplicity and flexibility of our
demonstrated scheme enables fluxonium-based remote entanglement architectures.
