Unhackable quantum messages travel 158 miles without cryogenics for first time
SMRTR summary
Scientists have transmitted unhackable quantum messages over 158 miles of existing fiber-optic infrastructure without cryogenic cooling, a first for practical quantum key distribution (QKD) over such distances. The Toshiba Europe team used commercial optical fiber and simpler equipment like avalanche photodiodes. Although current transmission is slow at 110 bits per second, researchers aim to increase speed and distance to secure communications against future quantum computer attacks.
