Experimental measurement-device-independent type quantum key distribution with flawed and correlated sources. (arXiv:2204.08323v3 [quant-ph] UPDATED)
cs.CR updates on arXiv.org arxiv.org
The security of quantum key distribution (QKD) is severely threatened by
discrepancies between realistic devices and theoretical assumptions. Recently,
a significant framework called the reference technique was proposed to provide
security against arbitrary source flaws under current technology such as state
preparation flaws, side channels caused by mode dependencies, the Trojan horse
atttacks and pulse correlations. Here, we adopt the reference technique to
prove security of an efficient four-phase measurement-device-independent QKD
using laser pulses against potential source imperfections. We present …
