IBM Buys HRL Laboratories to Add 18-Qubit Silicon-Spin Technology
3 articles · Updated · IBM · Jul 23
Summary
IBM signed a definitive agreement to acquire HRL Laboratories, aiming to speed its quantum roadmap by adding HRL’s silicon-spin qubit engineering and broader quantum R&D portfolio.
HRL’s appeal centers on spin qubits built with standard semiconductor tools, which IBM said offer a credible scaling path alongside superconducting qubits and can operate at about 1 kelvin versus 0.015 kelvin.
A recent HRL prototype used 54 quantum dots across three rails to support up to 18 qubits, demonstrating one- and two-qubit gates and small-scale error-detecting codes.
Beyond computing, IBM said the deal also brings quantum sensing, networking and materials research that could improve future qubits, semiconductors and a wider quantum internet strategy.

Overview
IBM has entered into a definitive agreement to acquire HRL Laboratories, aiming to significantly advance its quantum computing initiatives. This move is driven by IBM’s long-term vision to deliver useful quantum computing to the world. The acquisition, expected to close by the end of the third quarter of 2026 after customary closing conditions and regulatory approvals, brings HRL’s talented team and advanced technologies into IBM’s ecosystem. By combining HRL’s expertise with its own, IBM strengthens its dual quantum strategy, positioning itself to accelerate the development of scalable and practical quantum systems for future applications.
