One of the supercomputing centres I most like to work with is Pawsey Supercomputing in Australia. Their green credentials are quite amazing. Touring the facility, we see the use of a natural aquifer and solar power for the cooling system. As detailed here: pawsey.org.au/our-green-cr...

52% of the USA's Fortune 500 companies have disappeared since the year 2000. The current AI narrative might be a function for entropy in the market, but there's likely as many leaders treading water that would have drowned post-ZIRP, as there are "disruption" stories. 2026 will be interesting.

This time around, he tackles HSBC's recent claims for a "34% [quantum] advantage in predictions of financial trading data". It's an interesting read, to say the least. scottaaronson.blog?p=9170

HSBC unleashes yet another “qombie”: a zombie claim of quantum advantage that isn’t
Today, I got email after email asking me to comment on a new paper from HSBC—yes, the bank—together with IBM. The paper claims to use a quantum computer to get a 34% advantage in predic…

In our Quantum Computing community, we have no shortage of "interesting characters". Some of those have become celebrities in their own rights, like Scott Aaronson, who's blog has become a go-to destination for the inevitable "well actually" post after any overly enthusiastic press release.

It's nearly time to talk about a new project we're releasing. The best thing is it's open source, it's for the community, and it's something I know a lot of product teams in Quantum Computing will benefit from. Providing value doesn't always need to be technical or complicated. More on this soon.

Here's a look behind the scenes as I get ready for a conference in Tokyo. I've been too busy to do the (overdue) planned headshot photography session, so I wondered... could AI help me repurpose my general avatar? Spoiler: the result in the second image is unintentionally hilarious.

I keep thinking about a comment I read. Making me think about all the various local maxima we are experiencing in our current lives, that will zoom off in new directions as progress (and entropy) rolls forward: "Trebuchets are what you get when your Physics knowledge outpaces your Chemistry".

Generally an interesting example of how experimentation on the available (NISQ-era) quantum computers yields new forms of near-term algorithms. Not quite replacing classical methods for packing air freight, but great progress in hybrid methodology. More here: www.linkedin.com/posts/hellod...

I read the new IonQ and Airbus white paper about #quantumcomputing for transport logistics optimisation so you don't have to... TLDR? A new Multi-Angle Layered Variational Quantum Algorithm (MALVQA) that uses fewer two-qubit gates than standard QAOA approaches, and a novel cost function.

If you've worked on the commercial side of quantum, you know this pain, keeping up with market trends and data across industries, personas, and specific algorithms. So I've collected it for you, and organised it in those streams. Going live today, and populating over the weekend.

I got tired of juggling multiple platforms for content publishing, and I wanted to see all my content in one view. Bebop is my custom CMS built for content campaigns --> Hashnode, Dev, Bluesky, and Mastodon are working, and there's a built-in local blog too. v0.2.3 is on Github.

Ironically this kind of thing is why I'm building Bebop as an open source project. It's a tool to write/manage content locally but push across "the usual suspects" of blogging and content. Just not on Medium now - but Hashnode and Dev integrations are done.

David Ryan @davidryan.bsky.social · 02/02/2025
I miss the era of open APIs and developer advocacy being the norm. I lost a few hours tonight extending the Bebop CMS publishing module to include Medium. But the APIs and integration tokens are shut down, regardless of the developer site down out of date saying otherwise. My mistake 😬

Refer to my earlier comments that we're about to see Quantum Computing companies repositioning to align with the prevailing AI investments. Sovereign funds have propped up the VC pullback from quantum, but there's still a shortfall to be met. Projects like Stargate create the umbrella to do that.

When making developer docs, be sure to use the brightest whitest style possible, with tiny text, and the softest shades of grey the eye can barely detect on the screen. Making them work harder to read your content makes them appreciate it more, and earns their respect as a worthy challenge.

Want proper science insights? Find a few people who work in that field and just ask them. A tiny bit of effort gets us genuine insight. No effort makes us a passive consumer of garbage. And AI isn't making this any better (as the number of people quoting incorrect quantum AI quotes shows).

Pro tip: 90% of anything that the general media writes around science or technology is SEO keywords strung together to generate clicks. And 100% of what these generic "technology blog" sites do is just AI-generated nonsense stitching together as many current keywords as possible.
