description: "IBM has connected and cooled two modular cryogenic systems, marking a significant step in scaling quantum computers toward fault tolerance by 2029. The linked modules support hundreds of quantum chips, with initial tests achieving temperatures below 15 millikelvin. Each module offers 12 times more wiring space than current systems, facilitating chip-to-chip connections. This advancement supports IBM's roadmap to deliver the Quantum Starling system in 2029 and reach at least 1,000 programmable qubits by 2027."

# IBM connects first modular cryogenic systems to scale quantum computers toward 2029 fault tolerance

-   IBM connected and cooled two modular cryogenic systems, advancing its scale-up plan for fault-tolerant quantum computing. \* Linked modules target hundreds of quantum chips in a shared environment, supporting IBM’s plan to deliver Quantum Starling in 2029. \* Initial tests reached 4 Kelvin in under five days, then dropped below 15 millikelvin; combined system measures more than 8 feet tall. \* Each module provides up to 12 times more wiring space than widely used IBM quantum systems, enabling more chip-to-chip connections. \* Roadmap targets at least 1,000 programmable qubits by 2027 via L-couplers; Nighthawk processors slated for installation later this year.
