.@IBM reveals latest quantum processors—IBM Quantum Loon and IBM Quantum Nighthawk—and all future chips on our quantum development roadmap are being fabricated at the Albany NanoTech Complex (@CNSE) using 300mm semiconductor wafer technology: https://t.co/45p1ZwcMib #QDC25

Data centers dominate AI, but they're hitting physical limits. What if the future of AI isn't just bigger data centers, but local intelligence in our hands? The viability of local AI depends on intelligence efficiency. To measure this, we propose intelligence per watt (IPW):

This week, @StanfordAILab shared findings showing AI is entering a new era: from large models in the cloud to smaller, efficient ones running locally. In tests with IBM Granite 4.0, compact models handled 88.7% of queries, cutting energy and latency. ➡️ https://t.co/yGbvuG0BIo

And the @IBM Loon wafer made it to #Atlanta as well... #QDC

@IBM @CNSE The fabrication of IBM Quantum chips at the Albany NanoTech Complex—and the close synchronization between semiconductor experts and physicists across Albany and at the IBM Thomas J. Watson Research Center in Yorktown—is key to the success of quantum computing at IBM.

@IBM @CNSE This story is about more than processing quantum chips on larger wafers. It’s about using the best possible minds, machinery, and processes to realize quantum computing.

@IBM @CNSE The larger, 300mm wafer can carry more individual chips than its 200mm predecessor, allowing for more cost-effective chip yield per wafer and therefore providing shorter (faster) iteration and implementation cycle times.

Big news from @IBMResearch at #QDC25: major breakthroughs in processors, error correction, and fabrication are accelerating the path to fault-tolerant quantum computing. Here’s what’s new. 🧵

Congratulations to Abhinav Kandala from @IBMResearch on receiving the Rolf Landauer and Charles H. Bennett Award in Quantum Computing from @APSphysics for his outstanding contributions to developing and implementing error mitigation techniques: https://t.co/No0qe4YvVM

Speakers and attendees: Safe travels—we look forward to seeing you. Unable to attend? Stay tuned for updates, recaps, and announcements throughout the week.

Attendees will also have the chance to observe demonstrations of IBM Quantum Roadmap milestones from a practitioner’s perspective and gain a deeper understanding of how the platform is evolving toward advantage-grade workflows.

Key highlights include insights into recent advances in classical error mitigation and exploration of powerful new features introduced in the upgraded IBM Quantum Platform.

With an emphasis on practical experience with state-of-the-art tools and best practices, we’re strengthening our commitment to collaboration by focusing on workflows and capabilities that drive progress in three critical areas: Simulation, Optimization, and Quantum Information.

Bringing together computational scientists, researchers, developers, and educators from around the world, the IBM Quantum Developer Conference (#QDC25) will showcase the hardware and software that will enable users to find and extend quantum advantage on IBM Quantum systems.

@The_QEDC Touring the @IBMResearch Think Lab—our collaborative space designed to help visitors engage with these technologies—attendees experienced tangible IBM innovations firsthand, including our 2 nm nanosheet technology, AI accelerator hardware, and IBM Quantum System Two.

Yesterday, attendees of this year’s @The_QEDC annual meeting in NYC visited the IBM T.J. Watson Research Center in Westchester County, New York, to explore our work in advanced semiconductor manufacturing, AI, and quantum computing.

Last week I shared our recent arXiv paper detailing the world’s largest entangled state, with 120 qubits at 56% fidelity with a shot-retention rate of 28%, run on Heron R2 ibm_aachen. Now, with our new Heron R3 ibm_boston, we established a new record GHZ state on 140 qubits at

.@DARPA selects @IBM for Stage B of the Quantum Benchmarking Initiative, which aims to determine the feasibility of building a large-scale fault-tolerant quantum computer by 2033. The progression affirms our roadmap toward fault-tolerant quantum systems: https://t.co/nF7hwNaDF0

.@APSphysics awards @jaygambetta the 2026 George E. Pake Prize for expert leadership in the development and deployment of quantum computing technologies, as well as for making quantum computing accessible to researchers worldwide: https://t.co/wshOorNETt
