IBM announces new quantum processor, plan for starling supercomputer by 2029
IBM has unveiled an expanded roadmap for its quantum computing efforts, marking a significant milestone in the development of fault-tolerant quantum systems. The company aims to build IBM Quantum Starling, which it claims will be the world’s first large-scale, fault-tolerant quantum system, by 2029. This announcement follows the release of two new technical papers that IBM believes are crucial for achieving this goal [1].IBM’s roadmap outlines the progression of two new quantum systems: Starling and Blue Jay. Starling is set to be completed by 2029 and will be capable of 100 million quantum operations using 200 logical qubits. Blue Jay, due by 2033, will be able to execute 1 billion quantum operations using over 2,000 logical qubits. Both systems will be located at IBM’s quantum data center in Poughkeepsie, New York [1].
The first paper published by IBM focuses on quantum error correction, introducing quantum low-density parity check (qLDPC) codes. This approach aims to reduce the number of physical qubits needed for error correction, a critical aspect of fault-tolerant quantum computing. The second paper introduces a new heuristic decoder, Relay-BP, which will enable real-time error correction using conventional computing resources [1].
IBM’s shift to qLDPC codes is significant because it addresses the limitations of surface code approaches, which were previously considered impractical due to high engineering demands. This new approach is modular and more feasible to implement, marking a significant step forward in quantum error correction [1].
IBM’s plans for the next four years also include the introduction of the Loon processor, expected this year, which will allow for the testing of architecture components for the qLDPC code. Additionally, the Kookaburra multi-chip processor, scheduled for 2026, will combine quantum memory with logic operations, and the Cockatoo system, due in 2027, will connect two Kookaburra modules to further enhance the system’s capabilities [1].
The development of quantum computing is expected to revolutionize various industries, including healthcare, materials science, drug discovery, and cryptography. IBM’s advancements in this field could lead to breakthroughs in solving complex problems that are currently beyond the reach of classical computers [1].
