IBM Unveils “Quantum Starling”: World’s First Large-Scale Fault-Tolerant Quantum Computer by 2029

IBM has announced that by 2029 it will unveil the world’s first large-scale, fault-tolerant quantum computer—codenamed “Quantum Starling”—marking a pivotal advancement toward commercially viable and scalable quantum computing.

According to IBM’s roadmap, Quantum Starling will be housed in the company’s new quantum data center in Poughkeepsie, New York. Its projected computational power is anticipated to surpass that of current quantum systems by a factor of approximately 20,000, with the potential to overcome prevailing hardware limitations.

Achieving this performance would, in theory, require memory resources exceeding those of 1,048 of today’s most powerful supercomputers combined.

IBM revealed that the architecture of this fault-tolerant quantum computer will include hundreds, if not thousands, of logical qubits—robust quantum units capable of sustaining billions of computational cycles with stability. This capability is expected to serve as a cornerstone for accelerating drug discovery, advancing material science, enabling complex quantum chemical simulations, and solving intricate optimization problems—laying the groundwork for high-efficiency computation and industrial applications of the future.

In contemporary quantum technology, a logical qubit is a fundamental unit for error-resistant information storage, composed of multiple physical qubits. These physical qubits work collaboratively to detect and correct errors, thereby constructing logical units that are significantly more stable and capable of prolonged operation.

IBM emphasized that one of the most formidable challenges in building a large-scale fault-tolerant quantum system lies in creating a greater number of reliable logical qubits using the fewest possible physical qubits—an ambition that, until now, has lacked a clear and economically viable solution.

The forthcoming debut of Quantum Starling signifies a major technical breakthrough in addressing this issue and underscores IBM’s unwavering commitment and technical prowess in realizing practical quantum computation.

In the years ahead, IBM will continue to deepen its research into logical qubit design, quantum fault-tolerance mechanisms, and scalable computation architectures—laying the technological foundation necessary to transition quantum computing from the laboratory into mainstream application and advancing the maturity of the global quantum ecosystem.
