Google's overview of World Quantum Day focuses on recent breakthroughs and remaining hurdles, especially around error correction and scaling. It's optimistic but still realistic about timelines.

Google tends to balance hype with engineering reality better than most

Thoughts?

Still feels like we're closer than people expected even a few years ago
Error correction still seems like the biggest bottleneck
Scaling without stability is useless so this is where the real fight is

Is the world ready for it yet? Not half

[EventHorizon25]

Interesting to see how much of this is still experimental vs production-ready

Gonna be winds of change a coming next year

I have had mixed results with that approach. I keep a list of what I do to every fresh install so I can repeat it without thinking.

Give it a go and report back.

Bit fiddly but that is the right approach. Measure twice and all that, but also factor in that it always takes longer than you think.

Turned out alright when I did it.

The companies quietly working on PQC hardware are more interesting than the ones making headlines.

Basically my experience exactly. Start there and see if it makes a difference.

The gap between the labs and deployment in the real world is still massive.
