Quantum cryptography has entered the friendly skies. A precise beam of photons sent from an airplane allowed researchers on the ground to create a nearly unbreakable encryption key to protect information. The experiment, which was reported on March 31 in Nature Photonics, is an important step toward creating a secure global communication network based on beaming photons to and from satellites. [1]

I am just waiting to see the Basic Law of Cryptography applied here. You know... the Universal Unbreakable Law that states that every encryption (even the... unbreakable ones) will be eventually broken... 🙂
