We just put on arXiv a long haul work on "bending" the time-dynamic of the surface code. We demonstrate error suppression from distance 3 to 5 for three different implementations on Willow. The three offer uniques venues for new hardware. arxiv.org/abs/2412.14360

Two new papers from our team detailing how we optimize our gates and measurements. Our work on beyond-classical computation, Majorana edge modes, non-Abelian braiding and quantum error correction was enabled by these optimizations. arxiv.org/abs/2308.02321 arxiv.org/abs/2308.02079

Let me save you all a bunch of time. If ya see something about LK-99 from a blue checkmark with something vague about AI in their profile and an AI generated cartoon character profile pic, there’s a 99.9999% chance they have no clue what they’re talking about

As an experimentalist, seeing our work studied by other is extremely rewarding! I am really happy to see that our work sparked interest in the community!
Quantum Many-Body Physics @ Leeds@theoryleeds

We have performed large-scale classical simulations of @GoogleQuantumAI experiment on few-particle bound states in non-integrable XXZ circuits, finding more anomalous features in the dynamics: arxiv.org/abs/2307.13042 Thanks to @LeverhulmeTrust for support

Remember that paper from the end of last year that claimed it could factor 2048 bit integers using 378 qubits? At the time, I mentioned to Tanuj Khattar that a nice starter paper would be to just simulate it and verify it doesn't work. Here's the result: arxiv.org/abs/2307.09651

@letonyo @cdf1530 I read to quickly my bad! I didn’t caught the pessimism of the initial quote. Personally, I would say that quantum simulator have already delivered amazing experiments.

@AlexisMorvan1 @cdf1530 I don't know what it will be, but I expect it to be a true quantum algorithm, not some classical "quantum-inspired" algorithm.

@letonyo @cdf1530 What do you think will be the most important one? Imho, it pretty hard to predict “the most important one” and I would say the answer probably differ for different sensibilities. Many-Body physics is really a natural applications for quantum devices

This is definitely a possible outcome, but I'd be (badly) surprised if it was the most important one. @cdf1530

Very exciting to see @NoahGossQuantum highlighted for his work on qutrit CZ. This work is particularly close to my heart as it’s the culmination of my time at @BerkeleyLab . I really hope that we will see more qutrit results in the future!
Berkeley Lab Computing Sciences Area@LBNLcs

The experimental success👏of generating two-qutrit entangling gates with high fidelity was published in @NatureComms in 2022. R&D funded by @doescience led by AQT @BerkeleyLab w/ QNL @BerkeleyPhysics. Continue reading: bit.ly/qutrits_AQT #QuantumComputing #AQTatBerkeleyLab

@jmchow Could you run a Random Circuit Sampling experiment? I genuinely would be extremely interested in a result like this.

The leap is that we can do this with 100+ qubit and depth 60 and now beyond circuits. We certainly welcome this to be run on other quantum systems. While everyone waits how about ppl propose what else to run on these systems we are building.

The theorist at ⁦@GoogleQuantumAI⁩ have put together a manuscript detailing when quantum circuit are “classically hard”. They also show that the IBM 127 qubits experiment result is indistinguishable from a 28qubits classical simulation arxiv.org/abs/2306.15970

We prefer XEB at @GoogleQuantumAI :p Joke aside, I think for elements fidelity everyone has converged to some randomized benchmarking (and variant) and the comparison between plateforme is possible.
Paul Smith-Goodson@Moor_Quantum

Folks, isn't it about time we had a Quantum standard? @IBM & @QuantinuumQC use #QuantumVolume & IonQ_Inc uses #AlgorithmicQubits. Now @Azure Quantum has a metric called #rQOPS that counts operations that remain reliable for the duration of a practical quantum algorithm

@postquantum @BosonBulmer We spent a lot of time trying to push both classical and quantum execution of the RCS! Tensor network methods have proven to be quite good for these problem

@BosonBulmer Yeah, I certainly wouldn't bet against it. But given the back and forth we've seen, and (for example) this result is only from April, wouldn't you want to wait awhile before calling it?

Quantum snake-oil companies like @dwavequantum are advertising real-world applications for #QuantumComputing. Meanwhile, in the real real-world, there's still a tug-of-war battle to decide whether current quantum or classical devices are faster for sampling random numbers. 1/
Jake Bulmer@BosonBulmer

Massive result today on classical simulation of GBS. I personally believe that it means: **Gaussian Boson Sampling experiments no longer hold a quantum advantage** Huge congrats to Changhun Oh, Minzhao Liu et al. scirate.com/arxiv/2306.037…

We are packing up the UChicago lab and moving it to Stanford. opened up the fridge to remove our sample after a 2yr long cooldown (nice spaghetti Frankenstein setup). packing it under vacuum might have been excessive but I’m not taking any chances 😥

Our work on the braiding of non-Abelian anyon (the first experimental realization!) is finally out in Nature. It's quite amazing to see experiments observing these non-Abelian anyons that have escape experimental probe for so long.
Google Quantum AI@GoogleQuantumAI

Today in @Nature, @GoogleQuantumAI and collaborators have braided non-Abelian anyons for the first time. Unlike all particles observed so far, the state of two non-Abelian anyons changes when they are swapped, opening an exciting path in quantum computing nature.com/articles/s4158…
