Are we ready for a quantum leap in cloud security?

Depending upon your age, the phrase 'Quantum Leap' either conjures up images of Scott Baluka as the time-travelling physicist Dr Sam Beckett or the change of an electron from one quantum state to another. Those who are most likely to visualise the latter are now promising a quantum leap in the state of security in the cloud, courtesy of the very science-fiction sounding use of entangled states, superposition and blind quantum calculations.
