Quantum computer will be impossible to hack

The Futurist Magazine :
Quantum computing could make networks impervious to cyberattacks or render them defenseless. The race to be the first to build a large quantum computer, or quantum network, is a matter of national security, according to computer scientist Dave Bacon of the University of Washington. The goal is to harness the behavior of particles at the quantum level to enable faster computation. This could allow governments (or other users) to break otherwise impervious encryption codes, as well as to reverse the process and create essentially unbreakable codes.
