Breaking RSA-2048 with 23,000 cat qubits. 🐈 In 3.14 days This is the finding of our new paper, the latest resource estimate for Shor’s algorithm, the benchmark the whole field uses to compare quantum hardware 📄 The results are a record low for total quantum resources at this speed of execution, about 40 times fewer physical qubits than @GoogleQuantumAI 's Craig Gidney 2025 estimate. 🏁 RSA-2048 is the lock behind secure websites, banking and software updates 🔐 Shor's algorithm has been able to break it, on paper since 1994. Nobody has built the machine yet, but every year the estimate of how big it needs to be gets a little smaller. In 2019, the best estimate was 20 million qubits. In 2024, ours was just under 100,000. Now 22,593, in 3.14 days. Yes, pi 🥧 Small isn't enough. Fast isn't enough. The new study optimizes for both. 😼 Bitcoin, Ethereum and most blockchains aren't secure either, about 30,000 qubits would be needed to crack a Bitcoin key in about an hour ₿ ⏳ How we got here, what it means for cryptography, and when it all converges, our CEO Théau Peronnin talks about it in the blog 👇 📝 Blog - alice-bob.com/blog/our-estim… 📄 Paper - eprint.iacr.org/2026/2665 Stay curious, more info coming soon 👀 #QuantumComputing #CatQubits #ShorsAlgorithm #PostQuantumCryptography #Cryptography #FaultTolerance #DeepTech

A Satoshi Nakamoto statue was just unveiled in Vienna

Quantum is poised to become a multi-trillion dollar industry in the next few years. We think New Yorkers should share in that profit. That's why we negotiated that New Yorkers get board seats and a 15% stake of intellectual property that comes out of NYU's Quantum Fabrication facility. Because all New Yorkers should benefit from the economic success of this city.

alright guys, let's do both!

Justin Drake calls for crypto "bunker mode", warning ECDSA could break before Q-Day. But fresh addresses only help holders who can move. What about exposed keys and coins that never migrate: freeze, no freeze, or another way? Catch the QRL Show with @KonstantHacker and @Strike_Attack Today @ 11 AM ET youtube.com/live/d8MFDxhlXvA

This is why I always say “please” and “thank you” when talking to ChatGPT and Claude. Maybe it changes nothing today. But when the robots remember every conversation we’ve ever had, I’d rather be listed under “polite human.” Be nice—and you might be spared. 🤖

A major milestone for Infleqtion: 30 entangled logical qubits, working together in a single computation on Sqale. Using just 80 physical qubits, Infleqtion has delivered its 2026 roadmap milestone, becoming the first neutral-atom quantum computing company to reach 30 logical qubits on a commercial system. Congratulations to our Sqale hardware and Superstaq software teams on an extraordinary achievement. Their co-design made this possible, alongside an AI-assisted discovery that halves the physical gates needed for a key logical operation. Fewer gates mean fewer chances for error as we push toward larger, more complex computations. Next stop: 100 logical qubits in 2028, with customer application development already underway. Each advancement brings us closer to the goal: quantum computers that can tackle problems customers can’t solve today. Read the announcement: ow.ly/2vhu50ZQQcp Explore the science: ow.ly/YLxr50ZQQcm
