IBM Connects Its First Modular Cryogenic Systems in Milestone Toward Fault-Tolerant Quantum Computing
New cryogenic quantum fridges designed to link hundreds of quantum chips. Cooled to below 15 millikelvin, more than 180 times colder than deep space, the build out marks a step forward in the engineering required for future quantum computers. Advances IBM’s quantum roadmap to deliver the world’s first fault-tolerant quantum computer in 2029. New York, NY (Aug. 19, 2026) – IBM is pleased to announce it has successfully joined and cooled down two cryogenic modules into a single environment. The new architecture is designed to scale into the modular, shared, and ultra-cold system required to link hundreds of quantum chips into a more powerful quantum computer capable of solving large problems. Its deployment is a milestone on IBM’s path to delivering IBM Quantum Starling in 2029, which is expected to be the world’s first fault-tolerant quantum computer and will integrate advances across error correction, processor design, decoding, and systems engineering.

Combined, the first two operational modules stand more than 8 feet tall and 8 feet wide, and initial tests demonstrated they can jointly cool down to 4 Kelvin (the temperature of liquid helium) in under 5 days, reaching...
