Microsoft advances topological qubits with Majorana 2 chip for fault-tolerant quantum computing

Microsoft's Majorana 2 quantum chip advances topological qubit technology, aiming for fault-tolerant quantum computing. The chip uses a lead-based superconductor and a new semiconductor compound, significantly improving qubit coherence time and resilience to interference. Microsoft's AI platform, Discovery, played a key role in its development. This development is part of Microsoft's long-term strategy for quantum computing, which differs from competitors' approaches and aims for a scalable, error-corrected machine by 2029.
