The problem of disambiguation or researchers is valuable.
Google could solve this instantly by including the ORCID in profiles or copying the idea. (Sadly rumors suggest Google scholar is likely to be axed.)
I don't need my work history or academic papers displayed.

If I had to pick a favorite paper of the year, this would be among the top.
arxiv.org/pdf/2407.07694
Laserless single (99.99916) and two-qubit (99.97) gates. They bring a new paradigm for a platform that’s been going strong for 20+ years
(Also enjoy the integrated form factor)

At QTML 2024, I spoke about recent work with Robert Huang on "Learning shallow quantum circuits with many-qubit gates" (a.k.a. efficient learning of QAC^0 unitaries). In this ~15min talk I discuss the project motivation, key results, and high-level proof ideas.

Super bizarre folks.
It's funny that the Dwave CEO is his own stock troll.
This is my favourite workday of the year (better even than Nobel Prize in Physics announcement day!), because it's the day when my colleagues and I @physicsworld.bsky.social announce our selection of the year's most important advances in physics. 🧪⚛️🔭 #quantum

Pure gold
Omg I came across that thread just now
The thing I've noticed about quantum press releases is at the core there is usually a solid advance.
Unfortunately it gets butchered and hyped.
E.g. Nvidia and Google's recent releases.
I’m holding space for Google
Tech bros on Twitter be like:
I spent 2 minutes reading a press release on Google's paper about their quantum computer so you don't have to.
They claim to have .... blah blah...
But what is quantum computation?
Does it live up to the hype?
I, the expert, will break it down
Google's new hardware looks great and I'd be excited to try it out. But I seem to be even more interested in its limitations: Their repetition code results show an error floor at around 10^-10.
What physics is lurking down there? Can we tame it?
Google's new quantum computing chip Willow holds lots of promise and its error correction capability is a signature result. But the benchmark Google are using for its performance is, as their team told me, still an "IOU" for more practical calculations www.newscientist.com/article/2459...
Here’s Pete Shadbolt’s presentation at MIT Technology Review’s EmTech Summit, showing work that the company is doing to overcome hard technical challenges from the nanometer to kilometer scale.
Whoa this is crazy -- less than ppm single qubit gate errors! Ions have their issues but are just consistently impressive with developments like this

Movie I'm watching now, cast talking about a new special fighter jet. Pilot:
"I know a little bit about this. It's quantum processin', right?"
Tech guy:
"Yeah, it's the first tested application. Ten terabits a second."
And then they just move on...
Major cringe.
We are officially cool people! 🥶❄️
#cryo 🤩
New paper today!
scirate.com/arxiv/2411.1...
We run repetition codes of up to d=51 and 100 rounds. But rather than just taking the bit values from the measurement, we take the point on the IQ plane. Decoding using this information gives significant improvements, including passive leakage reduction.
Folks I always say: Just because it is published, that does not mean it is wrong!
Optical CV measurement-based quantum computation ... LET'S GO!

A Millimeter-Wave Superconducting Qubit
by Anferov, Wan, Harvey, Simon, Schuster
this is cool as
(1) they can operate 1K rather than mK - a huge advantage,
(2) there is less noise at 100GHz,
(3) microwave to optical transduction should be easier
arxiv.org/abs/2411.11170
Atom Computing from yesterday arxiv.org/abs/2411.11822
I think this is the most impressive demonstration they have posted todate
Today is a great day for quantum hardware on the arXiv!
First up is superconductors.
By using a high kinetic inductance material the Yale group makes an inductor that is compact, linear and low-loss.
Super cool. Could help with fluxonium qubits
arxiv.org/abs/2411.12611
Thank you!
Yeah wrong paper 🤦♂️
I have a question about this.
Was done on the Tsunami box (or whatever the current incarnation is called) ? Or is this completely new hardware infrastructure that enabled your results?
Bring on the bosonic codes ...heck yeah!
I'm pretty pumped about the recent Yale GKP qudit paper.
It's funny that PsiQuantum might set up shop in Queensland Australia, a place that has no shortage of photons.
How Dulwich Quantum and Quantum Memeing could together try to solve the collective action problem.
