  text: In this article, we propose a method for generating single microwave photons
    in superconducting circuits. We theoretically show that pure single microwave
    photons can be generated on demand and tuned over a large frequency band by making
    use of Landau-Zener transitions under a rapid sweep of a control parameter. We
    devise a protocol that enables fast control of the frequency of the emitted photon
    over two octaves, without requiring extensive calibration. Additionally, we make
    theoretical estimates of the generation efficiency, tunability, purity, and linewidth
    of the photons emitted using this method for both charge- and flux-qubit-based
    architectures. We also provide estimates of the optimal device parameters required
    for these architectures to realize the device.
