Quantum communications could soon allow secure communications that is faster and more convenient than one time pads.
Physicists have demonstrated the distribution of three entangled photons at three different locations (Alice, Bob and Charlie) several hundreds of meters apart, proving quantum nonlocality for more than two entangled photons.
Quantum key distribution (QKD) uses quantum mechanics to guarantee secure communication. It enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages. It is often incorrectly called quantum cryptography, as it is the most well known example of the group of quantum cryptographic tasks.
How much does this matter when personnel security management at top secret facilities have Bradley Manning, Edward Snowden and Russian and Foreign spies running around inside ?
The US and other countries have lost the discipline of keeping and managing secrets. Securing and encrypting communication lines does not matter when information is leaking like a sieve elsewhere.
The pipes may get secured to have no holes but the bathtub and sinks are leaking and contractors are told to connect the plumbing to enemy houses.
There is also the money in book deals, movie deals and tell-alls to television and internet media.
1. The US and many countries have too many things labeled secret that are not
2. If something really needs to be kept secret then you have to put in the effort to manage it as a real secret with compartmentalization
3. The secret keeping people have to recognize the money that can be easily made from movie and book deals for certain kinds of secrets
