Microsoft Unveils Majorana 2 Quantum Chip

Microsoft announced the topological quantum chip Majorana 2, enhancing qubit stability significantly.

Microsoft announced the topological quantum chip Majorana 2. The new processor features a lead-based material stack, enhancing qubit stability more than 1000 times compared to the previous generation.

According to the company, the qubit lifetime in Majorana 2 exceeds 20 seconds, reaching up to a minute in some cases. In comparison, Majorana 1 had a range of 1 ms to 12 ms.

Microsoft also achieved operation durations of about 1 μs and a qubit size of approximately 0.01 mm.

The key change in the new chip is related to materials. Many competitors, including Google and IBM, use aluminum conductors, whereas Microsoft switched to lead. According to the tech giant’s Vice President Jason Zander, this change enabled the 1000-fold improvement in performance.

The corporation aims to create a scalable quantum computer by 2029, having roughly halved previous timelines.

AI Assistance

Microsoft also stated that artificial intelligence accelerated material discovery and helped refine production. AI tools analyzed scientific research, searched for suitable compounds, automated measurements, optimized manufacturing processes, and identified defects affecting qubit reliability.

Simultaneously, the firm opened access to the Microsoft Discovery platform for research and development. It allows companies to create teams of AI agents, connect them to internal data and external scientific sources, build hypotheses, plan experiments, analyze results, and repeat the cycle.

The quantum team used Discovery to manage workflows.

Microsoft’s Corporate Vice President for Quantum Technologies Zulfi Alam called the automation of measurements with agentic AI a “turning point.”

In June, D-Wave Quantum revealed a roadmap for the phased development of quantum systems. By 2032, they plan to create a fault-tolerant quantum computer with 100 logical qubits.
