Reply #34: You can buy appliances that use this tech now.

They are essentially guaranteeing the security and integrity of the key exchange over secured data fiber optics.

The "rest" of the traffic between these devices travel over the normal frame relays and leased lines. But banks and telco's can essentially be more secure about how they securely communicate between two nodes using this technology.

As I understand these quantum crypto devices to work, they are only using the nonlocality for the key exchange and that in turn makes it more difficult to compromise key integrity for secure data exchanged over the secure fiber optic physical segment.

Thats what's kind of neat about this tech, you can buy it now, and have been able to for a few years.
