IBM unveils Starling quantum computer roadmap for 2029
IBM recently unveiled a detailed roadmap for its first large-scale, fault-tolerant quantum computer, named Starling, set to launch in 2029. The announcement, overshadowed by WWDC 2025, outlines a clear path to delivering a system capable of executing 20,000 times more quantum operations than current systems. Starling will be housed in a new IBM Quantum Data Center in New York and will require computational power equivalent to over a quindecillion (1048) of today’s fastest classical supercomputers.
The roadmap includes several milestones: Loon (2025), Kookaburra (2026), and Cockatoo (2027), each testing critical elements of error-corrected, modular architectures based on quantum LDPC (qLDPC) codes. These codes aim to reduce qubit overhead by 90%, marking a significant leap in quantum computing akin to the transition from vacuum tubes to transistors in classical computing.
IBM’s journey in quantum computing began in 2011 with the first 5-qubit processor. Subsequent advancements, such as 16-qubit and 50-qubit systems, remained in the “noisy intermediate-scale quantum” (NISQ) phase, limited by error rates and decoherence. The breakthrough came with IBM’s research on quantum LDPC codes, which provided a clear path to error-corrected logical qubits.
Starling’s fault-tolerant design addresses the inherent noise in quantum systems, where stray electromagnetic fields can flip qubit states. By bundling thousands of noisy physical qubits into a single logical qubit, IBM aims to exponentially reduce error rates. This technology is crucial for running meaningful algorithms and solving complex problems in drug discovery, optimization, and cryptography.
The roadmap extends beyond Starling, with plans for Blue Jay in 2033, which will perform 1 billion quantum operations on 2,000 logical qubits. While ambitious, IBM’s timeline faces competition from other tech giants like Google, Intel, Amazon, and Microsoft, all racing to achieve quantum computing breakthroughs.
