Scientists Hide Data in Heat Using 'Negative Light'
Physicists have invisibly transferred data disguised as background thermal radiation using a phenomenon called negative light, opening new frontiers in covert communication.
Key Takeaways
- Negative light encodes data in anti-correlated photon states indistinguishable from background heat
- Transmissions produce zero detectable electromagnetic signature
- Technology could enable truly undetectable military and intelligence communications
