IBM has successfully merged and jointly cooled two modular cryogenic systems, creating a single ultra-cold environment aimed at scaling resilient quantum systems.
The two modules are designed to connect hundreds of quantum chips within a more powerful infrastructure. According to IBM, the cooling process to 4 K took less than five days, after which the system achieved temperatures below 15 mK.
The company claims that each vacuum enclosure provides up to 12 times more wiring space than the most common quantum systems they offer. This enhancement is expected to increase the number of connections between the chips within the modules and across them.

By 2027, the company aims to link multiple processors into a system with at least 1,000 programmable qubits using L-couplers. With the anticipated launch of IBM Quantum Starling in 2029, IBM expects to house thousands of qubits in each module.
The plans for IBM Quantum Starling were unveiled in 2025 alongside a new error correction code. The integration of the two cryogenic modules is considered another milestone in this roadmap.
In July, IBM’s CEO Arvind Krishna mentioned that investments in quantum computing are expected to significantly impact the company’s revenue and profits by 2028 or 2029.
