IBM Unveils Starling: First Fault-Tolerant Quantum Computer Targets 2029
IBM's Starling, a 2029 fault-tolerant quantum leap, promises 20,000x power and unprecedented AI innovation.
June 10, 2025

International Business Machines (IBM) has unveiled an ambitious roadmap to construct the world's first large-scale, fault-tolerant quantum computer by 2029. This pioneering system, dubbed IBM Quantum Starling, will be housed in a new, dedicated IBM Quantum Data Center in Poughkeepsie, New York.[1][2][3] The company projects that Starling will deliver a staggering 20,000-fold increase in computing power compared to current quantum systems, a leap that could redefine computational capabilities across numerous fields, including the rapidly advancing sector of artificial intelligence.[1][2][4][3][5] This initiative signals a significant shift from experimental quantum devices towards practical, scalable, and error-corrected quantum supercomputing.[1][6][7]
At the heart of IBM's strategy is the pursuit of fault-tolerance, a critical hurdle in the development of truly useful quantum computers.[6][2][8] Quantum systems are notoriously susceptible to errors caused by environmental noise and the inherent fragility of qubits, the fundamental units of quantum information.[8][9][10] These errors accumulate and can corrupt complex calculations, limiting the capabilities of current "noisy" intermediate-scale quantum (NISQ) computers.[9][11] Fault-tolerance aims to overcome this by employing quantum error correction codes, where information is encoded across multiple physical qubits to create a more robust "logical qubit."[1][9] IBM's approach leverages a novel error-correction technique using quantum low-density parity-check (qLDPC) codes, which the company states can reduce the number of physical qubits needed for error correction by approximately 90% compared to other leading methods, significantly improving efficiency and scalability.[12][4][13][14] The Starling system is slated to utilize 200 logical qubits, built from an estimated 10,000 physical qubits, and will be capable of executing 100 million quantum operations, or gates.[15][1][13][3] To put its projected power into perspective, IBM claims that representing the computational state of Starling would necessitate the memory of more than a quindecillion (10^48) of the world's most powerful classical supercomputers.[1][4][14]
The development of Starling is part of a meticulously planned roadmap that includes several intermediary quantum processors designed to test and integrate the necessary technologies.[12][14] The IBM Quantum Loon, expected this year, will test architectural components for the qLDPC codes, including "C-couplers" for longer-distance qubit connections within a chip.[12][3][14] Following this, IBM Quantum Kookaburra, anticipated in 2026, will be the first modular processor designed to store and process encoded information, combining quantum memory with logic operations – a key building block for multi-chip fault-tolerant systems.[15][12][14] In 2027, IBM Quantum Cockatoo is planned to demonstrate the entanglement of two Kookaburra modules using "L-couplers," linking quantum chips together to avoid the challenge of building impractically large single chips.[15][12][14] These advancements are designed to culminate in the Starling system in 2029.[1][14] Beyond Starling, IBM envisions an even more powerful system, IBM Quantum Blue Jay, targeted for 2033, which is projected to feature 2,000 logical qubits and be capable of executing one billion quantum operations.[1][6][13] While full fault-tolerance is the 2029 goal, IBM expects to achieve "quantum advantage" – where quantum computers can outperform classical computers on specific tasks – as early as 2026 by leveraging error mitigation techniques.[15][16]
The implications of a large-scale, fault-tolerant quantum computer for the AI industry are profound.[17][18] AI, particularly machine learning and deep learning, relies heavily on processing vast datasets and performing complex calculations, often matrix operations, for training models.[17][18] Quantum computers promise to revolutionize these tasks by offering potential exponential speedups in certain algorithms.[17] This could lead to significantly faster training of more complex AI models, allowing them to tackle problems currently intractable for classical computers.[17][18] Areas within AI that could see substantial benefits include enhanced optimization for fine-tuning machine learning models, more efficient data processing and classification of large datasets, and improvements in natural language processing.[17] The development of better quantum machine learning algorithms could enable AI to solve complex problems in fields like drug discovery, materials science, financial modeling, and logistics optimization with unprecedented speed and accuracy.[1][6][17][18] Furthermore, AI itself can play a role in advancing quantum computing by helping to discover better error-correcting codes and optimizing quantum hardware design and control.[17] The synergy between fault-tolerant quantum computing and AI is expected to unlock new frontiers in scientific research and industrial applications.[17][19]
In conclusion, IBM's commitment to delivering the Starling fault-tolerant quantum computer by 2029, housed in a new dedicated quantum data center and boasting a 20,000x power increase, represents a pivotal moment in the quantum computing journey.[1][2][3][5] The focus on achieving robust error correction through innovative qLDPC codes and a modular design approach addresses key challenges that have historically hindered progress.[6][12][4][14] While significant engineering hurdles remain, the detailed roadmap provides a clear path forward.[12][16][14] The successful realization of Starling and its successors could provide an immense computational advantage for various industries, with the AI sector standing to gain substantially from the ability to train more sophisticated models and solve complex problems far beyond the reach of current supercomputers, heralding a new era of accelerated innovation.[1][6][17][18]
