Google has devised a means for securing HTTPS certificates against quantum computing attacks without massive performance hits stemming from the considerably longer size of data required to be included.

Is anyone following this work?

@dangoodin My question is, how close are we to hardware that can do quantum attacks on encryption?

@tknarr @dangoodin don't forget how slow certain technology adoption rates are.
You only need one person to have the capabilities to use quantum computer for this meanwhile every website needs to update which will take a while

@thibaultmol @dangoodin Yes. It won't be just one person though, just as it wasn't just one person who got the first computer made using ICs. It'll be a steady progression across such a large set of organizations that there'll be no way not to broadcast the state of the hardware. We'll know well before the first unit that can do the job in a reasonable amount of time is produced.

The question needs asked and answered: what's the earliest we can reasonably expect the first one...

@thibaultmol @dangoodin ... that can do the job at all to arrive? Without a timeframe, planning a response is a bad idea. You need a response in place before that deadline, but if you rush things you end up with sub-par results that won't hold up against the inevitable advances. So we really need to know if we're on a 5 year deadline vs. 10, 25, 50.

Personally I think it's closer to 50 than 10.

This is the NSA timeline for PQC. Other countries (EU, UK, etc.) have similar timelines between 2030 and 2035.

I, however, do not think that we will have any Cryptographically Relevant Quantum Computers (CRQC) in the next decades.
