• Abstract: The problem of implementation security in quantum key distribution (QKD) refers to the difficulty of meeting the requirements of mathematical security proofs in real-life QKD systems. Here, we provide a succint review on this topic, focusing on discrete variable QKD setups. Particularly, we discuss some of their main vulnerabilities and comment on possible approaches to overcome them.

  Coherent-one-way (COW) quantum key distribution (QKD) is a significant communication protocol that has been implemented experimentally and deployed in practical products. Existing security analyses of COW-QKD either provide a short transmission distance or lack immunity against coherent attacks in the finite-key regime. We present a tight finite-key framework for a variant of COW-QKD, which has been proven to extend the secure transmission distance in the case.

• Secure quantum key distribution with a subset of malicious devices [0.0]
  Malicious manipulation of quantum key distribution (QKD) hardware is a serious threat to its security. One possible approach to re-establish the security of QKD is to use a redundant number of devices. We introduce an efficient distributed QKD post-processing protocol and prove its security in a variety of corruption models of the possibly malicious devices.

• Quantum key distribution with correlated sources [1.7499351967216341]
  In theory, quantum key distribution (QKD) offers information-theoretic security. In practice, however, it does not due to discrepancies between the assumptions used in the security proofs and the behaviour of the real apparatuses. Here, we close this gap by introducing a simple yet general method to prove the security of QKD with arbitrarily long-range pulse correlations.
