Harvard Physicists Build World's Longest Secure Quantum Network Using 22 Miles of Fiber-Optic Cables.
Harvard physicists have created the world’s longest secure quantum communications network, spanning 22 miles using fiber-optic cables. Published in Nature, their experiment used "entanglement" to connect two quantum nodes, enabling unhackable data sharing.
Physicists at Harvard University have created the world’s longest secure quantum communications network, spanning 22 miles using existing fiber-optic cables. Published in Nature, their experiment connected two quantum computer nodes via "entanglement," allowing unhackable data sharing over this distance.
This breakthrough comes as the world prepares for “Q Day,” when quantum computers could break current encryption methods. Major institutions are already adopting new protocols, but no secure data transmission method exists yet.
Quantum data's unique properties prevent it from being copied or transmitted traditionally. Instead, data is "entangled" at both points, allowing for secure teleportation. This makes quantum systems potentially unhackable.
Currently, quantum networks like Harvard's could become the primary medium for sensitive data distribution. Institutions might use quantum entanglement to securely share information, revolutionizing data security and potentially safeguarding digital assets like cryptocurrency against network-based attacks.
