(Phys.org)—In the ongoing effort to make communications secure, Quantum Key Distribution (QKD) theoretically provides a solution – but to the delight of increasingly sophisticated hackers, falls short in real-world systems ...
For the first time, physicists have experimentally demonstrated a quantum secure direct communication (QSDC) protocol combined with quantum memory, which is essential for storing and controlling the transfer of information. ...
As malicious hackers find ever more sophisticated ways to launch attacks, China is about to launch the Jinan Project, the world's first unhackable computer network, and a major milestone in the development of quantum technology.
