To add to that: a QKD with one-time pad[1] is proven secure. However, because many QKD implementations have low secret key rates (the highest in research is 10Mbps[2]; most commercial implementations do only a few Kbps) you won’t be doing high-bandwidth communication using that method.

- leetbulb 8y agoThe author of OP article really needs to read that Toshiba press release. Good layman explanation. Also, I figured that the bottleneck came from the amount of entangled photons that could be generated. Interesting to know that it's a hardware/software issue on the detector and post-processing side.
