| Space Station Could Beam Secret Quantum Codes by 2014When two particles such as photons are born from the same event, they emerge entangled, meaning they can communicate instantaneously no matter how far apart they are. Transmitting entangled pairs of photons reliably is the backbone of so-called quantum key distribution—procedures for converting those pairs into potentially unbreakable codes. 1 votes by wal on 2008-06-12 |
