Among various implementations of QKD, the entanglement-based approach is especially promising for future applications, as it forms the basis of device-independent quantum secure cryptography, holds the potential for yielding high bit rates, and facilitates networks without trusted nodes. I will present our recent work about long-distance (fiber-based and free-space) entanglement based QKD experiments. (DOI:10.1073/pnas.1818752116, 10.1038/ncomms15971).
