By using quantum dots and smart encryption protocols, researchers overcame a 40-year barrier in quantum communication, ...

Measurement-device- independent QKD protocols can successfully close all the loopholes at detectors by introducing an untrusted intermediate node for interference measurement.

A team of physicists at the Hebrew University of Jerusalem has made a breakthrough that could bring secure quantum ...

Quantum key distribution (QKD) is the mostly-unused, super-secure protocol that even defeats the big nosy ears of the NSA. But QKD is quite difficult to get right. And, just like with classical ...

The protocol, dubbed device independent quantum key distribution, was first proposed three decades ago but had not been realized experimentally before due to technical limitations, which the ...

MicroCloud proposes a high-dimensional quantum key distribution protocol enhancing secure quantum transmission using quantum Fourier transform. How does the new QKD protocol improve security?

BT trialed QKD on a six-kilometer-long cable – still far off other experiments with the protocol in which researchers have managed to deliver quantum particles over hundreds of kilometers.

Party line: the new protocol allows 10 parties to share information securely. (Courtesy: University of Witwatersrand) A “quantum secret sharing” scheme that allows 10 parties to share information ...
