No practical quantum supremacy or anything like it has been demonstrated has it? Is it sort of expected that will co-occur with QC breaking encryption? I'm just trying to gauge how "almost here" this actually is, or if it's still talk
- bawolff 4y agoQuantum supremacy is a much much much lower bar than breaking rsa (at normal key strength)
- advisedwang 4y agoCloudflare estimates 15-40 years[1]. Cloudflare, Google [2], Amazon [3] and others are all at various phases of moving to post-quantum algorithms. My own lesson from the Snowden revelations is that if we're close enough to a security break that the possibility is well understood, there's a very high chance someone is already doing it.
