(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 ...
Quantum communication—where information is sent through particles, typically entangled photons—has the potential to become the ultimate secure communication channel. Not only is it nearly impossible to eavesdrop on quantum ...
