India, Aug. 25 -- IBM 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 (t...
