IBM Unveils 12-Fridge Quantum Cooling System to Link 50 Chips by 2030

IBM introduced modular cryogenic systems designed to keep quantum chips a few thousandths of a degree above absolute zero while scaling machines to thousands of stacked chips.
Two refrigerator units together stand more than 8 feet tall and 8 feet wide, and new L-coupler superconducting cables let qubits pass information between boxes without leaving the cryogenic environment.
Later this year, IBM plans to install its first working processor with hundreds of qubits for testing, followed by a machine with at least 1,000 programmable qubits next year.
By the end of the decade, IBM aims to connect 12 fridges and 50 processor chips, a scale it says could improve fault tolerance and reduce the stop-start resets that plague current quantum experiments.
That stability push targets future uses in molecular chemistry, drug development and materials science, where quantum systems are expected to tackle problems beyond classical computers.
