IBM has announced its roadmap to develop IBM Quantum Starling, the world’s first large-scale, fault-tolerant quantum computer, to be built at the new IBM Quantum Data Center in Poughkeepsie, New York, by 2029. Unveiled on June 10, 2025, this breakthrough aims to deliver unprecedented computational power, enabling transformative advancements in fields like drug development and materials discovery.
IBM Quantum Starling to launch by 2029 in New York.
First large-scale, fault-tolerant quantum computer.
Performs 20,000 times more operations than current systems.
Uses qLDPC codes, cutting 90% of error-correction overhead.
Targets drug development, chemistry, and optimization.
Roadmap includes Loon, Kookaburra, and Cockatoo processors.
IBM Quantum Starling is set to redefine quantum computing with its ability to perform 20,000 times more operations than today’s quantum systems. Using 200 logical qubits, Starling will execute 100 million quantum operations, with its computational state requiring the memory of over a quindecillion (10^48) supercomputers. “IBM is charting the next frontier in quantum computing,” said Arvind Krishna, Chairman and CEO, IBM. This scalability positions Starling to tackle complex challenges in chemistry, optimization, and drug discovery.
The key to Starling’s fault tolerance lies in quantum low-density parity check (qLDPC) codes, which reduce error-correction overhead by approximately 90% compared to traditional codes. This innovation minimizes the number of physical qubits needed, making large-scale quantum computing feasible. IBM’s technical papers detail how qLDPC codes enable efficient processing and real-time error correction, overcoming engineering challenges that previously limited scalability.
Starling’s architecture is designed for modularity and efficiency, supporting hundreds of logical qubits to run complex algorithms. Upcoming processors in IBM’s roadmap—Quantum Loon (2025), Kookaburra (2026), and Cockatoo (2027)—will test critical components like C-couplers and L-couplers for long-distance qubit connections and modular scaling. This approach avoids the need for impractically large chips, ensuring practical infrastructure and energy use.
By enabling fault-tolerant quantum computing, Starling will accelerate innovation in industries requiring high computational power. Its ability to run billions of operations with minimal errors will enhance materials discovery, optimize supply chains, and streamline drug development. The system’s real-time decoding and universal instruction capabilities ensure reliable performance for enterprise applications.
IBM’s vision for Quantum Starling marks a pivotal step toward practical quantum computing. By addressing error correction and scalability, IBM is paving the way for a new era of computational breakthroughs, empowering businesses to solve previously intractable problems.
