IBM says 'Loon' chip shows path to useful quantum computers by 2029
News Summary
IBM announced it has developed a new experimental quantum computing chip named 'Loon,' marking a significant stride towards achieving useful quantum computers by 2029. This development addresses the inherent error-proneness of quantum chips, which are crucial for solving problems beyond classical computers' capabilities. IBM's approach, first proposed in 2021, involves adapting cellphone signal algorithms for error correction, running on a hybrid of quantum and classical computing chips. While this method makes quantum chips more complex to build due to the need for advanced quantum connections between qubits, industry analysts like Gartner's Mark Horvath commend its ingenuity. IBM leveraged the Albany NanoTech Complex for its advanced chipmaking tools. Although 'Loon' is still in early stages without external testing dates, IBM also unveiled 'Nighthawk,' a chip set for release by the end of 2025. The company expects 'Nighthawk' to demonstrate 'quantum advantage' on certain tasks by the end of 2026 and plans to share its code openly with researchers for community validation.
Background
The field of quantum computing aims to harness quantum mechanical phenomena to perform computations intractable for classical computers. However, the inherent fragility of quantum systems makes them highly prone to errors, which has been a significant barrier to practical applications. IBM has a long history in quantum computing research and is one of the key players in the field, alongside tech giants like Alphabet (Google) and Amazon, working to overcome the core challenge of error correction. The company proposed a novel framework for quantum error correction in 2021, utilizing signal processing algorithms, aiming to enhance reliability by integrating both quantum and classical computing components.
