🚨 Job alert! 🚨 The group of Principal Investigator @steventouzard.bsky.social is looking for a Research Fellow. The candidate will be part of a well-funded initiative to create quantum networks using Erbium ions in solid-state and integrated photonics. 📥 Apply: careers.nus.edu.sg/job/Research...

ArXiv quant-ph needs to be split up! Paul Ginsparg lists Daniel Gottesman's proposed subcategories at his @aspenphysics.bsky.social talk. He is looking for feedback: please reply, dm, or email.

The startup, launched in 2020, is focusing on improving its devices before it enters a commercialisation phase. #QuantumComputing #StartupEurope

Happy to share our work with @anthony-leverrier.bsky.social, @christophe.vuillot.info, Jérémie Guillaud and Mazyar Mirrahimi on the LDPC-cat architecture was published in Nature Communications! Thanks to the reviewers for their useful feedback www.nature.com/articles/s41...

What a brilliant start of the year with two experiments from @qcrew-sg.bsky.social published in PRX Quantum! Both are investigations we did using a single qubit coupled to a cavity in the standard bosonic cQED systems, which are small devices but such rich #quantum playgrounds! Links below 👇

Mathematical physicist Cécile DeWitt-Morette was born #OTD in 1922. She made foundational contributions to Feynman functional integrals, organized the first American conference on general relativity (important for gravitational waves), and started the Les Houches Summer School. 🧪 ⚛️ 👩‍🔬 (1/n)

We've been getting a lot of questions about alternate QEC codes, and are we looking into any? Yes! Here's experiments for two on Willow. The color code: arxiv.org/abs/2412.14256 Dynamic surface codes: arxiv.org/abs/2412.14360

A disheartening paper, signed by an esteemed and admired researcher. The attempt to quote a record breaking number leads to an equivalent disappointment when you realize there is no attempt (and even dishonesty) regarding QNDness.

Here is the referee report for that paper. :) Same would apply here.

Congratulations to all who contributed to the advances in quantum error correction recognized by the Physics World Breakthrough of the Year. physicsworld.com/a/two-advanc...

Great timeline of quantum supremacy claims and refutations by Tom Wong on X. x.com/thomasgwong/...

Came here looking for the quantum crowd. Super excited to see the lively discussions on not only #quantumphysics but also #scicomm, #womeninSTEM, and many more. Here is my team @qcrew-sg.bsky.social and I, pleased to be here! 😇

These slides are great and seems to address all the clouds of Quantum Computing. Here are my (obviously) favorite ones as they highlight the clear vision of a few actors, starting 10 years ago now (and making great progress)

It is now official as it is on the blog. My summary: - Excited for the QEC results - Remember that computation claim cannot be verified classically, need better test algorithms for QC - Funny Gil Kalai bit (although why platforming him? I had mostly forgotten him) scottaaronson.blog?p=8525

Check out Willow, our latest chip from Google Quantum AI!

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 am absolutely thrilled to see Google crushing milestones after milestones in quantum computing, in particular in quantum error correction! (Quickly leaving the NISQ era behind). Here is some personal anecdote regarding this precise Quanta article👇🏻 www.quantamagazine.org/quantum-comp...

I was thrilled to hear about the surface code when Alexei Kitaev visited @caltech.edu in April 1997. It's heartening to see the hardware catching up with the theory of quantum error correction. There's still far to go but this is encouraging progress. www.quantamagazine.org/quantum-comp...

Thanks for highlighting our work!

Today #quantum arXiv selection: Single qubit gates errors at 10^-7 level, mapping for wavepacket dynamics, enhanced qubit readout via reinforcement learning, Bayesian quantum amplitude estimation, and optimized molecular vibrational dynamic. More details and links below:

Hey this is Yvonne’s work, check it out!

Mark your calendars! The second big lecture series of the term on #quantum #science and #technology at @ethzurich.bsky.social will be given by one of the pioneers of mesoscopic physics and superconducting quantum circuits Michel Devoret. - math.ethz.ch/news-and-eve... Hope to see you there.

Alice & Bob has released its new quantum roadmap. alice-bob.com/wp-content/u...

Hi all! I just uploaded my recently defended thesis, I hope you like it. Hit me up if you want to chat about anything GKP/QEC or life. :) arxiv.org/abs/2412.02442

Any feedback on Alice&Bob roadmap? Quantum computing in 5 years with cats, requiring 200x less qubits than qubit based architectures? alice-bob.com/roadmap/

So that’s where the Quantum community went (I guess with LinkedIn). I think Bluesky could make a cozy refuge as the other platform becomes unliveable!

If the universe started out in a pure quantum state, how is anything in a mixed state now?
