Security of quantum key distribution with light sources that are not independently and identically distributed
2016 · Physical Review A
Although quantum key distribution (QKD) is theoretically secure, there is a gap between the theory and practice. In fact, real-life QKD may not be secure because component devices in QKD systems may deviate from the …

Quantum key distribution with setting-choice-independently correlated light sources
2019 · npj Quantum Information
Abstract Despite the enormous theoretical and experimental progress made so far in quantum key distribution (QKD), the security of most existing practical QKD systems is not rigorously established yet. A critical obstacle is that almost …

1 × <i>N</i> DWDM channel selective quantum frequency conversion
2025 · Optics Express
Dense wavelength division multiplexing (DWDM) is a key technology for realizing high-capacity and flexible quantum communication networks. To enable the emerging quantum internet, quantum frequency conversion is also essential for bridging different quantum systems over …
