India has demonstrated a breakthrough in quantum cryptography by successfully transmitting quantum‑encrypted keys across a 5.56 km free‑space optical link, marking the first “un‑cable” quantum key distribution (QKD) test. The experiment recorded a quantum bit error rate under 5 %…

India has sent quantum encryption keys across 5.56 km of open air without fibre‑optic cables, using quantum key distribution (QKD) to share a secret cryptographic key via optical signals. The test kept the quantum bit error rate below 5%…

Key developments this week show a multi‑front push toward quantum‑resistant security. A new GAO report flags that U.S. agencies are lagging on post‑quantum encryption, warning that sensitive data remain exposed to future quantum decryption. Meanwhile, the National Institute…

A wave of recent actions shows both policymakers and private firms moving faster to guard data against the coming threat of quantum computers. A GAO report warned that most U.S. federal agencies are still lagging—only one of 24…
