AFAIK, this is not so much 'quantum computing', but rather 'quantum encryption'. Quantum encryption takes advantage of quantum entanglement, which means that the states of two particles in the same quantum system are physically linked, regardless of the distance between them. Quantum computing usually refers instantaneous information transfer within a processor, and potentially, infinitely fast computation. I believe that quantum computing takes advantage of entanglement as well, but for the instantaneous nature of the quantum information transfer, and not for its inability to be intercepted.
