Quantum computing is entering a new phase of commercial momentum.

Companies exploring pilots now—from finance to pharma to logistics—may be best positioned to capture billions in value as the technology matures.

@pmddomingos This plot is outdated. As per recent results from Google and Caltech at 10k qubit we already expect utility applications. This is due to innovation in error correction for neutral atoms and ions that can do better than surface code scaling

Hahah, this is hilarious — Bitcoin influencers forced to explain quantum mechanics.

[Simply Bitcoin @SimplyBitcoin]

Jeff Booth, Jack Klucznik and Nicholas Marino perfectly explain how a Quantum threat to Bitcoin is "nonsense."

"Bitcoin is the answer. Bitcoin is physics."

The risk is very real device capabilities surprise even experts. We already have few quantum computers that can do beyond classical tasks and that list is gonna grow in coming years. Breaking bitcoin in 2030 is realistic with right amount of targeted investments, no major scientific breakthroughs are needed, mostly engineering ones

[Hrant Gharibyan ⚛️ @qhrant]

@nvk highly recommend reading recent papers on neutral atoms and trapped ions. remarkable progress in fidelities and scalability has been achieved and consensus is being formed of scientific quantum advantage. Good place to start https://t.co/HMDkGidVae

[nvk 🌞 @nvk]

Quantum field is so far from having scaled devices to actually do the computation in reality that most of the paper claims are indistinguishable from scams.

[Hrant Gharibyan ⚛️ @qhrant]

@Excellion before taking such a strong position, highly recommend looking into capabilities of current quantum computers and recent quantum advantage claims. Probably a good starting point is @BlueQubitIO paper https://t.co/HMDkGidVae

It’s been almost 10 years since the Blocksize Wars ended and Brian hasn’t changed at all.

He still carries the exact same complete lack of humility and understanding. Brian forms the opinion first, along with a prescribed course of action and timeframe, instead of starting by understanding the nuanced problem and tradeoffs.

Solving the QC problem later rather than sooner is the best course of action.

➡️ Hastily changing from ECDSA/Schnorr to PQ signatures may make Bitcoin vulnerable to classical computing attacks today. Simply put: make Bitcoin safe against quantum computers just to get pwned by normal computers.

➡️ PQ signatures will likely be 10-125x larger than current ones, and massively reduce throughput. Possibly paving the way for Blocksize Wars 2.0. (h/t @_jonasschnelli_)

➡️ Proposed PQ solutions could be a Trojan horse to implement backdoors for RNGs or PQ encryption schemes. There are examples of the NSA doing this, first discovered by cypherpunk researchers and later confirmed by @Snowden leaks.

Given that quantum computers don’t actually exist and likely won’t exist for another 10-20 years, the worst possible course of action is to rush a fix. That’s not to say work shouldn’t be done to prepare, and there is already much work being done.

If you’re still worried about quantum computing, you should know that Coinbase wallet infrastructure is vulnerable to QC because of address reuse. In fact, that’s the default for Coinbase Prime, which serves institutional clients. So Brian should probably fix this first.

Physician, heal thyself.

@craig_clement Looks like @Excellion needs the convincing haha

[Claude @claudeai]

You can now enable Claude to use your computer to complete tasks.

It opens your apps, navigates your browser, fills in spreadsheets—anything you'd do sitting at your desk.

@demishassabis @elonmusk There’s no convincing evidence yet that AI can predict the quantum properties of matter—the very bedrock of fundamental science. We might just have to give it the keys to a quantum computer.

[Hrant Gharibyan ⚛️ @qhrant]

@davidasinclair Any big recent discovery (that’s easy to explain) driving this progress?

🚀 iQuHack is in full motion at @MIT ! ⚛️

Just wrapped up an amazing weekend here on campus. It was great to be back at my alma mater and see hundreds of students competing in the hackathon -- both on campus and across the world -- with top students solving hard peaked circuits puzzles.

Huge congrats to the winners! 🏆

It is exciting to see the remarkable growth of the quantum community globally. A big thank you to the organizers for putting together such a great event. We will be back next year! 🔥

@JKeynesAlpha @LiebermanAustin This is not true for all quantum devices. Here my team presents a problem that quantum can solve in hours that will take years in largest supercomputers. I will pay 20k if you prove me wrong https://t.co/laggdBzucB

[Secretary Marco Rubio @SecRubio]

Today, Armenian Foreign Minister @AraratMirzoyan and I announced the Trump Route for International Peace and Prosperity (TRIPP) Implementation Framework. It builds on the commitments of @POTUS’s historic peace summit just five months ago between Armenia and Azerbaijan. The TRIPP will unlock the South Caucasus’ potential in trade, transit, and energy flows—boosting prosperity and security throughout the region.

🚨: Google’s quantum chip solved in five minutes a problem that would take 10 septillion years.

Physicists say it “proved” we live in a multiverse!

[Google Quantum AI @GoogleQuantumAI]

We demonstrated verifiable quantum advantage with Quantum Echoes. Running 13,000x faster than leading supercomputers, this represents a significant step toward real-world applications. Watch → https://t.co/3WJWnISWZr

@preskill @VitalikButerin you might find this advances in quantum comptuing interesting. Particularly results on verifiable quantum advantage by @BlueQubitIO (https://t.co/HMDkGidVae)
