Quantinuum is generating truly random encryption keys using QC systems. The correlated noise in some QC systems is low-enough to guarantee truly random key generation... so a useful application to enhance high-value computer/information security.

- jl2718 5y agoIs this really that much of a problem? Like, even if you only get 1 random bit out of 100, you just sample and hash 100 times as many samples. What can you do with quantum noise that you can’t do with thermal noise?
- mikewave 5y agoI'm amazed they've been able to make a business out of this. At D-Wave, we have been able to generate truly random numbers for aeons; we use them for calibration, but they don't have any real business value presently. Truly random RNGs have been commercially available for ages, and if you need such a high level of randomness, you're probably sensitive enough that you don't want to accept them from some 3rd party over the internet. If you want some quantum-generated random numbers, sign up for D-Wave Leap and you can trivially generate your own for free... or perhaps, run an optimization algorithm to do something a little more useful.
