Microsoft has announced its latest breakthrough in quantum computing with the launch of the Majorana 2 chip, unveiled at its Build 2026 conference. The company says the new technology could pave the way for commercially viable quantum computers by 2029, marking a significant step forward in next-generation computing. According to Microsoft, the Majorana 2 chip is around 1,000 times more reliable than its previous generation. The company also claims a major improvement in qubit stability, with an average coherence time of up to 20 seconds, and in some cases extending to one minute, addressing one of the biggest challenges in quantum computing.
The new chip replaces traditional aluminum-based designs with a lead-based superconductor, which Microsoft says helps protect qubits from external interference and improves overall system reliability. This advancement is expected to enhance precision and scalability in quantum systems. Microsoft also highlighted the role of its AI-driven research platform, Microsoft Discovery, in accelerating development. By analyzing decades of quantum research data, AI systems have helped identify hidden patterns and speed up experiments that previously took weeks to complete. The company believes that advancements like Majorana 2 could transform fields such as healthcare, energy, agriculture, and scientific research by enabling faster and more powerful problem-solving capabilities than conventional computers.
