IBM commits $10 billion to fault-tolerant quantum computers by 2029 - qz.com

IBM has pledged $10 billion to develop fault-tolerant quantum computers by 2029, marking its largest-ever investment in quantum technology to accelerate practical, error-corrected systems. The initiative aims to overcome decoherence and noise—key barriers in quantum computing—by integrating advanced error correction, new qubit designs, and scalable architectures within seven years. Partnerships with academia, governments, and private-sector leaders will drive R&D, focusing on materials science, cryogenics, and quantum software to enable reliable, large-scale quantum operations. IBM’s roadmap targets interim milestones, including 100,000-qubit systems by 2026 and modular quantum processors by 2028, bridging today’s noisy devices to future fault-tolerant machines. The move intensifies the global quantum race, positioning IBM to lead in industries like drug discovery, logistics, and cryptography once fault tolerance is achieved.
