IBM Links Modular Cryogenic Cells to Scale Multi-Chip Architectures for 2029 Starling Quantum Computer
IBM has linked modular cryogenic cells, a step toward scaling multi-chip superconducting quantum processors for its 2029 Starling quantum computer. The milestone demonstrates a path to connect multiple refrigeration units, allowing larger qubit counts than a single cryostat can support.

Within two years, IBM could use linked cryogenic cells to prototype multi-chip logical qubit experiments spanning separate refrigeration units, testing distributed fault-tolerance before the full Starling system is built.
The linked cells provide the physical infrastructure to couple chips across cryostats. If interconnects preserve qubit coherence and thermal stability, IBM can begin integrating multiple processors now rather than waiting for a monolithic 2029 machine.
