Physicists at Toshiba’s Cambridge research labs have mapped out their vision of the next three generations of IT security. Speaking at an event put together by the Cambridge-MIT partnership, Toshiba scientist Andrew Hammond described how current quantum key distribution systems like MagiQ will be superseded. Though it apparently produces unbreakable encrypted optical comms, the current generation, which has been sold to a few defence agencies and telco R&D departments, relies on a variety of fudges to run. The weak laser light source cannot produce the individual photons an ideal quantum crypto solution would have.
