Researchers experimentally demonstrated a space-to-ground QKD network using a compact QKD terminal aboard the Chinese Space Lab Tiangong-2 and four ground stations.

Compact QKD System Paves the Way to Cost-Effective Satellite-Based Quantum Networks

OPTICA

Researchers report an experimental demonstration of a space-to-ground quantum key distribution (QKD) network using a compact QKD terminal aboard the Chinese Space Lab Tiangong-2 and four ground stations. The new QKD system is less than half the weight of the system the researchers developed for the Micius sa

Grace Robertson, recent alumna of Embry-Riddle University

Aviation Week 20 Twenties Inductee Sends Hope to Girls in STEM

Grace Robertson has always been one of the few women in the room throughout her training to become a space industry worker — and that makes sense, considering that women represent less than 12% of global aerospace engineers. But, she says, that’s “just a statistic.” “As children, we dream of becomi
