Microsoft Unveils Majorana 2 Chip, Targets 2029 Quantum Computer With 1,000-Fold More Reliable Qubits

3 articles · Updated · Microsoft · Jun 2

Majorana 2 gives Microsoft qubits with a mean 20-second lifetime—sometimes up to one minute—supporting a new goal of a commercially useful scalable quantum computer by 2029.
A new lead-based materials stack and agentic AI tools in Microsoft Discovery drove the gains, improving qubit reliability 1,000-fold while helping automate measurements, optimize fabrication and spot hidden flaws.
Microsoft also made Discovery generally available for enterprise R&D, letting organizations deploy AI agent teams for hypothesis generation, experiment design and validation with security and governance controls.
A free early-preview Discovery app can run locally with a GitHub Copilot account, extending the same AI-assisted research approach Microsoft says its quantum team already uses across disciplines and data silos.
