Automated machine learning for secure key rate in discrete-modulated continuous-variable quantum key distribution. (arXiv:2201.09419v2 [quant-ph] UPDATED)
cs.CR updates on arXiv.org arxiv.org
Continuous-variable quantum key distribution (CV QKD) with discrete
modulation has attracted increasing attention due to its experimental
simplicity, lower-cost implementation and compatibility with classical optical
communication. Correspondingly, some novel numerical methods have been proposed
to analyze the security of these protocols against collective attacks, which
promotes key rates over one hundred kilometers of fiber distance. However,
numerical methods are limited by their calculation time and resource
consumption, for which they cannot play more roles on mobile platforms in
quantum networks. …
