We’ll be showing a preview of Beryllium at Q2B. Beryllium is an object-oriented language that allows developers to build ever higher levels of abstraction. If you are at Q2B, you can visit the stand for a demo of Beryllium and more.
Today, we announced the debut of Beryllium, an object-oriented language allowing developers to start with simple building blocks and progressively create richer, higher-level structures by reusing and extending what they have already defined.

Delighted to see this paper finally out. I had the initial discussion with @aspuru.bsky.social that set us on this path well over a decade ago. Well done to my co-authors who did all the real work.
New in Digital Discovery: An example of shedding light on chemistry via dynamics.

We propose a method that uses dynamics to circumvent a notoriously hard problem when simulating molecules on a quantum computer: the preparation of initial states.

Now I have a quantum computer. Ho ho ho.
Today, we announce that we have completed the assembly and integration of a first quantum computer at our Singapore HQ. The system is now fully operational, making us the first quantum software company to own and run a quantum computer. youtu.be/kyioaNDohPc

If you're at #APSSummit25 and interested in what we're doing, drop by the stand to say hi to the team.
Unfortunately, I can't make it myself, but you're in good hands with Philip, Angelina, Jessica, Pooja and Denis.

Since there is less than an hour left in 2024 here, I guess I need to make a new year prediction for quantum computing for the coming year. Here it is: now we're past the error correction threshold, we're going to find that qubit lifetimes will increase super exponentially with time.

Spotted at a cablecar station in Tromso, in the very north of Norway. The hazards seem to be slip, trip, fall from a height and James Bond.

Another year, another Q2B, another reason to visit @computerhistory.bsky.social. Who’s going to be first to get a dilution refrigerator on display there?

Our paper on distributed blind computing is out on Arxiv! In short: we performed gates on our spin qubits remotely using photons without our nodes knowing what we did - all thanks to distributed matter-light entanglement 🥳

I’ve convinced our marcomms team that quantum twitter has been moving over here.
Our CEO @jfitzsimons.bsky.social and Chris Ballance of Oxford Ionics took the stage at @websummit.bsky.social in Lisbon to discuss the rapid evolution of quantum computing and its far-reaching implications.

It took me longer than I am prepared to admit to come up with this dumb joke.
Cold weather is clearly a big advantage for doing low temperature physics. This is known as the Leiden frost effect.

I had the chance to visit Bluefors today in Helsinki. CQT may have made Singapore the coolest place on the equator, but I can’t help thinking that there is a reason Singapore didn’t spawn the world’s leading manufacturer of dilution refrigerators.

Question for quantum bluesky: Which PhD students are doing the most interesting QC work at the moment? All the people I thought were PhD students now have tenure.

If you’re a quantum physicist, you should watch Oppenheimer. I have no time for the Oppenheimer-envy that so many in AI seem to be experiencing. The parable of Oppenheimer for physicists is about the weight of the work of those that went before. It’s our Iron Ring.

Ok, since the quantum computing crowd mostly haven’t arrived yet, maybe it’s a sign I should shake up who I follow. Who’s worth following on here? Science, tech, startups or just generally interesting or amusing.
