IBM Links Modular Cryogenic Cells to Scale Multi-Chip Architectures for 2029 Starling ...

IBM has connected its first modular cryogenic cells in New York, achieving operational temperatures below 15 millikelvin as a key milestone toward its 2029 fault-tolerant Starling quantum computer. The modular approach expands wiring space and enables scalable multi-chip integration via L-coupler quantum interconnects, targeting 1,000 programmable qubits by 2027.
