IBM Connects Cryogenic Modules to Advance Quantum Computing

IBM announced a significant technical breakthrough on Wednesday, August 19, 2026, successfully integrating and cooling two modular cryogenic systems for its quantum computing platform. The achievement marks a critical step toward the company's goal of deploying a fault-tolerant quantum supercomputer named Starling, which it aims to deliver by the end of the decade.

The development centers on a new, box-shaped cryogenic architecture designed to link hundreds of quantum processors within a shared ultracold environment. Each module, standing over eight feet tall and wide, was cooled to 4 Kelvin in less than five days and subsequently reached temperatures below 15 millikelvin, conditions essential for quantum chip operation. The system is currently operational at an IBM facility in Poughkeepsie, New York.

"This successful connection and operation of these cryogenic modules signals a leap forward" toward fault-tolerant quantum computing, said Jay Gambetta, IBM's director of research. He added that the milestone will accelerate progress alongside continued innovation in quantum hardware, software, and algorithms.
