If the MagiQ boxes are reliable, if they integrate well into existing networks, if they really are easy to manage, and if the company gets its certifications in place, then there is no reason why a CSO wouldn't want to consider this approach to secure high-speed corporate linksespecially those that go over the public fiber infrastructure. QKD could be just the thing for encrypting transmissions between a bank's headquarters and its data centeror for encrypting that link between the data center and a backup location. On the other hand, I don't think that we'll ever see quantum cryptography going to the desktop. But, who knows? "Ever" is a long time.
