IBM will build monster 10,000-qubit quantum computer by 2029 after 'solving science' behind fault tolerance — the biggest bottleneck to scaling up
- IBM scientists have reportedly solved a major challenge in quantum computing, paving the way for a large-scale, fault-tolerant quantum computer by 2029.
- Their research showcases new error-correction techniques, allowing for a system 20,000 times more powerful than current quantum computers.
- The studies introduce novel error mitigation and correction methods, improving hardware scalability significantly.
- The upcoming 'Starling' system will feature 200 logical qubits composed of around 10,000 physical qubits, with subsequent advancements in 'Blue Jay.'
- IBM's quantum LDPC codes mark a breakthrough in fault-tolerance, making the scaling of quantum computers an engineering challenge rather than a scientific hurdle.
- Quantum computers today excel in solving specific problems but face challenges in scalability and error correction due to the noisy nature of qubits.
- Error correction is critical in quantum computing, driven by the susceptibility of qubits to errors, which can hinder calculations.
- The new error-mitigation techniques, like LDPC codes, aim to reduce physical qubit requirements and enhance encoding rates significantly.
- IBM's future quantum architectures, such as Loon, will integrate these advancements, aiming for faster error mitigation and scalable quantum operations.
- The roadmap includes 'Starling' and 'Blue Jay,' expected to achieve impressive quantum operation capabilities using logical qubits.
