Quantum net is amazing, but not impenetrable. If the technology was released for public use, and someone had a need for the info, it will eventually be cracked. I dont see how this would be a mainstay in the foreseeable future anyways as the photons used decay after a short distance. Much like DC current back in the day, an entirely different system would need to be set in place before it could be useful.
Quantum physics is a branch of physics which deals with physical phenomena at microscopic scales, where the action is on the order of the Planck constant. Quantum mechanics departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter.
