Development of microwave single photon detectors in lumped element and traveling wave architectures

ORAL

Abstract

Detection of microwave photons is an important capability for superconducting quantum computing and microwave quantum optics. Promising single photon detectors have been demonstrated at microwave frequencies, but a single detector with high quantum efficiency, non-destructive detection, a low dark count rate, and broad detection bandwidth has thus far not been demonstrated. An enticing prospect is using the traveling-wave architecture, which has been used for broadband near-quantum-limited Josephson parametric amplifiers, for detection of discrete signals. Here we report progress towards experimental demonstration of single photon detection in lumped-element and traveling wave devices.
