IBM has announced a major step toward building the world’s first large-scale, fault-tolerant quantum computer, Starling, projected for delivery by 2029. The initiative includes a new quantum data center and technical breakthroughs in error correction using qLDPC codes.
IBM has unveiled its path to build the world's first large-scale, fault-tolerant quantum computer, setting the stage for practical and scalable quantum computing. Delivered by 2029, IBM Quantum Starling will be built in a new IBM Quantum Data Center in Poughkeepsie, New York and is expected to perform 20,000 times more operations than today's quantum computers.
To represent the computational state of an IBM Starling would require the memory of more than a quindecillion (1048) of the world's most powerful supercomputers. With Starling, users will be able to fully explore the complexity of its quantum states, which are beyond the limited properties able to be accessed by current quantum computers.
IBM, which already operates a large, global fleet of quantum computers, is releasing a new Quantum Roadmap that outlines its plans to build out a practical, fault-tolerant quantum computer. A large-scale, fault-tolerant quantum computer with hundreds or thousands of logical qubits could run hundreds of millions to billions of operations, which could accelerate time and cost efficiencies in fields such as drug development, materials discovery, chemistry, and optimization.
Starling will be able to access the computational power required for these problems by running 100 million quantum operations using 200 logical qubits. It will be the foundation for IBM Quantum Blue Jay, which will be capable of executing 1 billion quantum operations over 2,000 logical qubits.
IBM Quantum Loon, expected in 2025, is designed to test architecture components for the qLDPC code, including "C-couplers" that connect qubits over longer distances within the same chip. IBM Quantum Kookaburra, expected in 2026, will be IBM's first modular processor designed to store and process encoded information. It will combine quantum memory with logic operations — the basic building block for scaling fault-tolerant systems beyond a single chip. IBM Quantum Cockatoo, expected in 2027, will entangle two Kookaburra modules using "L-couplers." This architecture will link quantum chips together like nodes in a larger system, avoiding the need to build impractically large chips.
