IBM’s 2028 Quantum Computer: Error Correction and Scalability Plans Revealed
IBM intends to construct what it claims will be the world’s first large-scale, error-corrected quantum computer by 2028, with cloud access anticipated by 2029. The proposed machine, named Starling, will be a modular system built within a new data centre in Poughkeepsie, New York state. This development aims to address a key technical challenge in quantum computing – maintaining the stability of quantum bits (qubits) – and positions IBM to compete with Google, Amazon Web Services, QuEra and PsiQuantum. The company asserts it has resolved the core issues relating to quantum error correction, transitioning from theoretical research to practical engineering implementation.
IBM intends to construct a large-scale, error-corrected quantum computer, designated Starling, with anticipated availability via cloud access by 2029. This ambitious project centres on resolving a critical challenge: quantum error correction, essential for achieving reliable quantum computation. Quantum bits, or qubits, inherently succumb to decoherence and environmental noise, introducing errors into calculations, necessitating robust error correction schemes. The machine will be assembled from a modular architecture housed within a new data centre in Poughkeepsie, New York, leveraging advancements across multiple engineering disciplines.
A central claim underpinning this development is the transition from the scientific principles of error correction to the practical engineering required for implementation at scale. The modular design of Starling facilitates scalability and maintainability, allowing for increased qubit counts and computational capacity. This approach contrasts with monolithic designs and offers a pathway to building systems exceeding the limitations of current quantum processors.
The chosen modular architecture also facilitates incremental upgrades and scalability. The system’s design prioritises minimising latency and maximising qubit connectivity, reducing demands on cryogenic infrastructure. This architecture is a response to the complexities of maintaining coherence across a large number of qubits.
While the construction of Starling represents a significant undertaking, the interplay between quantum computing and classical simulation techniques will likely define the trajectory of scientific computing in the coming decade. IBM believes its integrated approach, encompassing algorithm development and chip packaging, provides a competitive advantage over other industry participants, including Google, Amazon Web Services, QuEra and PsiQuantum.
IBM’s success will be measured not only by qubit count but by sustained, low error rates and the development of practical algorithms. The company’s holistic approach to system integration and the modular architecture are intended to accelerate the field and establish a leading position. The data centre in Poughkeepsie will provide the necessary classical computing resources for error correction and algorithm development. The modular design allows for continuous improvement and the integration of new technologies.
