  1. 1. Analysis of Atmospheric Muon Bundles with IceCube

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Anna Selina Neyer; [2024]
    Nyckelord :;

    Sammanfattning : This work is a preliminary study of the background of a search for dark, long-lived particles in the IceCube detector. The high flux of atmospheric muons in IceCube is considered background to the detector's primary science goal, which is to detect astrophysical neutrinos through the emission of Cherenkov radiation.

  3. 2. Generation and detection of entangled single-photon pairs

    Kandidat-uppsats, Uppsala universitet/FREIA

    Författare :Gabriella Tesfamichael Habtezion; [2024]
    Nyckelord :;

    Sammanfattning : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. LÄS MER

  4. 3. Quantum Espionage

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Carlo Ninic Svensson; [2023]

    Sammanfattning : This thesis investigates the security of optical fiber communication and demonstrates the feasibility of eavesdropping using different tapping methods and superconducting nanowire single-photon detectors (SNSPDs). Methods for surveillance against fiber intrusion are also investigated. LÄS MER

  5. 4. Beyond Pulse Position Modulation : a Feasibility Study

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Danielle Gustafsson; [2023]
    Nyckelord :telecommunications; pulse position modulation; error-correction;

    Sammanfattning : During the thesis work, a feasibility study of the BPPM error-correction protocol is performed. The beyond pulse position modulation (BPPM) protocol was invented at Ericsson AB and describes a modulation encoding using vertically and horizontally polarized single photons for optical transmission and error-correction.
