  1. 1. Development of a QRNG front-end for shot noise measurement : analysis of quantum shot noise originating from photodiodes

    University essay from Linköpings universitet/Informationskodning

    Author : Martin Clason; [2023]
    Keywords : shot noise; quantum random number generator; photodiode; transimpedance amplifier; skottbrus; kvantslumptalsgenerator; fotodiod; transimpedansförstärkare;

    Abstract : As one of the more mature quantum technologies, quantum random number generators (QRNGs) fill an important role in producing secure and private keys for use in cryptogra- phy in e.g. quantum key distribution (QKD) systems. Many available QRNGs are expen- sive and optical QRNGs often require complex optical setups. READ MORE

  3. 2. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

  4. 3. Statistical Analysis of Dark Counts in Superconducting Nanowire Single Photon Detectors

    University essay from KTH/Fysik

    Author : Anton Cakste; Martin Andrae; [2022]
    Keywords : Single-Photon Detector; SNSPD; Dark Counts; Quantum Random Number Generator; Afterpulsing;

    Abstract : In this paper we perform a statistical analysis of dark counts in superconducting nanowire single photon detectors (SNSPDs) with the end goal of creating a quantum random number generator (QRNG) using these dark counts. We confirm that dark counts are Poissonian for low bias currents and that no afterpulsing is present. READ MORE
