Microsoft’s Majorana 2 chips push quantum computing toward practicality by 2029

Microsoft unveils Majorana 2, a next-gen topological quantum chip that replaces aluminum with lead and updates the semiconductor region, boosting qubit lifetimes from milliseconds to tens of seconds (with some devices exceeding a minute). Built on an improved material stack and aided by Microsoft Discovery’s agentic AI, the company says the roadmap to a scalable, practical quantum computer has been halved, targeting 2029, and it’s releasing Discovery to customers to accelerate R&D.

Quantum-Inspired Method Cracks Massive Quantum Materials in Seconds

A quantum-inspired algorithm using tensor networks lets researchers rapidly simulate enormous, non-periodic quantum materials such as topological quasicrystals and super-moiré systems (up to 268 million sites). By encoding colossal quantum spaces, the method achieves speeds unreachable by conventional computing, potentially accelerating the design of quantum materials and topological qubits and enabling future quantum computers to reduce heat in AI data centers; validation may follow in real quantum hardware via ongoing Finnish infrastructure projects.

Microsoft Demonstrates Unique Parity Lifetimes in Topological Qubit Prototype

Microsoft researchers demonstrated a prototype tetron qubit capable of performing two distinct quantum measurements with significantly different lifetimes, supporting progress toward topological quantum computing, though further validation and improvements are needed to confirm topological behavior and reduce error rates.

Physicists achieve nonabelion-based topological quantum states.

Physicists have created non-Abelian anyons, a type of exotic particle that could help make quantum computers less error-prone. The particles exist only as information inside a quantum computer, but their linking properties could make quantum computers more fault-tolerant. The researchers used a quantum computer to create virtual particles and move them around so that their paths formed a Borromean-ring pattern. The appearance of the pattern was confirmed by measurements of the state of the ions during and after the operation.
