Scientists are planning to create a network in the Chicago area tapping the principles of quantum physics. The idea is to prove that quantum physics could provide the basis for an unhackable internet.

This, they say, could have wide-ranging impact on communications, computing and national security.

The quantum network development, supported by the US Department of Energy (DOE), will stretch between the DOE’s Argonne National Laboratory and Fermi National Acceleratory Laboratory, a connection that is said will be the longest in the world to send secure information using quantum physics.
