  1. 1. A Classical-Light Attack on Energy-Time Entangled Quantum Key Distribution, and Countermeasures

    Författare :Jonathan Jogenfors; Jan-Åke Larsson; Arnt Inge Vistnes; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Quantum Key Distribution; Energy-Time Entanglement; Quantum Information; Kvantkryptering; Energi-Tid-Snärjning; Kvantinformation;

    Sammanfattning : Quantum key distribution (QKD) is an application of quantum mechanics that allowstwo parties to communicate with perfect secrecy. Traditional QKD uses polarization of individual photons, but the development of energy-time entanglement could lead to QKD protocols robust against environmental effects. LÄS MER

  2. 2. Breaking the Unbreakable : Exploiting Loopholes in Bell’s Theorem to Hack Quantum Cryptography

    Sammanfattning : In this thesis we study device-independent quantum key distribution based on energy-time entanglement. This is a method for cryptography that promises not only perfect secrecy, but also to be a practical method for quantum key distribution thanks to the reduced complexity when compared to other quantum key distribution protocols.
