Advantages of Asynchronous Measurement-Device-Independent Quantum Key Distribution in Intercity Networks. (arXiv:2302.14349v1 [quant-ph])
cs.CR updates on arXiv.org arxiv.org
The new variant of measurement-device-independent quantum key distribution
(MDI-QKD), asynchronous MDI-QKD or called mode-pairing MDI-QKD, offers similar
repeater-like rate-loss scaling but has the advantage of simple technology
implementation by exploiting an innovative post-measurement pairing technique.
We herein present an evaluation of the practical aspects of decoy-state
asynchronous MDI-QKD. To determine its effectiveness, we analyze the optimal
method of decoy-state calculation and examine the impact of asymmetrical
channels and multi-user networks. Our simulations show that, under realistic
conditions, aynchronous MDI-QKD can …
