Waveguide photon-number-resolving detectors for quantum photonic integrated circuits

Abstract

Quantum photonic integration circuits are a promising approach to scalable quantum processing with photons. Waveguide single-photon-detectors (WSPDs) based on superconducting nanowires have been recently shown to be compatible with single-photon sources for a monolithic integration. While standard WSPDs offer single-photon sensitivity, more complex superconducting nanowire structures can be configured to have photon-number-resolving capability. In this work, we present waveguide photon-number-resolving detectors (WPNRDs) on GaAs/Al0.75Ga0.25As ridge waveguides based on a series connection of nanowires. The detection of 0–4 photons has been demonstrated with a four-wire WPNRD, having a single electrical read-out. A device quantum efficiency of ∼24% is reported at 1310 nm for the transverse electric polarization.

  • In Si-based QKD transmitter demonstrations, secret key rates of kbps-Mbps and low quantum bit error rates of 1.0%-5.4% were obtained, and all implementations used external laser sources and weak coherent photon states.

    “In these demonstrations, secret key rates of kbps-Mbps and low quantum bit error rates of 1.0%-5.4% were obtained, and all implementations used external laser sources and weak coherent photon states.”

    From Integrated photonic quantum technologies (2020) · cites this paper as [66]

    The detector experiments described in the supplied copy use attenuated and pulsed lasers, but they are not Si-based QKD transmitter demonstrations. Searches for secret-key rates, quantum bit error rates, and external-laser or weak-coherent-state use across QKD implementations found no passage addressing the claim; the reported percentages concern detector efficiency instead.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
