  • Loss-tolerant prepare and measure quantum key distribution protocol 
    Mafu, Mhlambululi; Sekga, Comfort; Senekane, Makhamisa (Elsevier B.V. on behalf of African Institute of Mathematical Sciences, 2021-11-07)
    We propose a modified version of the Bennett–Brassard 1984 quantum key distribution protocol intended to tolerate losses, certain forms of noise, and the so-called photon number splitting attack. These are the issues ...
  • Reference frame independent twin field quantum key distribution with source flaws 
    Sekga, Comfort; Mafu, Mhlambululi (IOP Publishing Ltd, 2021-04-14)
    The trade-off between distance and secret key generation rate remains one of the major challenges in the practical implementation of quantum key distribution (QKD). As a solution, a twin field QKD protocol was proposed by ...
  • Security of quantum-key-distribution protocol by using the post-selection technique 
    Sekga, Comfort; Mafu, Mhlambululi (Elsevier B.V., 2021-05)
    The post-selection technique was proposed by Christandl, König, and Renner [Phys. Rev. Lett. 102, 020504 (2009)] to simplify the security of quantum-key-distribution schemes. This work applies this technique to derive the ...
