Networks of tiny, inexpensive sensors scattered
throughout an environment could make it easier to monitor
environmental conditions, collect scientific data and
track people and vehicles for military and law enforcement
purposes. Managing these sensor networks and analyzing
the data they collect, however, promises to be challenging...

It Works: Quantum cryptography
Perfectly secure communications comes down to using the
quirks of quantum physics to reliably detect eavesdroppers.
