Microsoft Accelerates Quantum Computer Goal with Majorana 2 Chip
Microsoft unveiled its Majorana 2 quantum chip, featuring qubits 1,000 times more reliable than its predecessor, boasting a 20-second mean lifetime. The company used agentic AI to speed development and now targets a practical quantum computer by 2029, halving its previous timeline. This marks a significant step towards commercially viable quantum computing.
Key points
- Microsoft announced its new Majorana 2 quantum computing chip at its Build conference.
- The chip's qubits are reportedly 1,000 times more reliable than the previous generation, with a mean lifetime of 20 seconds.
- Microsoft attributes the accelerated development to its agentic AI platform, Discovery.
- The company has halved its timeline, now aiming for a scalable, practical quantum computer by 2029.
- This development positions Microsoft to potentially achieve commercially valuable quantum computing by the end of the decade.
Microsoft has unveiled its next-generation quantum computing chip, dubbed Majorana 2, marking a significant acceleration in the company's roadmap.
Announced at the Build conference, the Majorana 2 chip features qubits that are claimed to be 1,000 times more reliable than its predecessor. These qubits achieve a mean lifetime of 20 seconds, a substantial improvement over previous generations and many competing quantum computing approaches, which typically measure lifetimes in microseconds. Some instances of Majorana 2 qubits have reportedly lasted as long as a minute.
Microsoft credits the rapid progress to the integration of agentic artificial intelligence, specifically through its Discovery research platform. This AI technology was used to optimize materials science, fabrication processes, and measurement automation, thereby speeding up the chip's development.
Fueled by these advancements, Microsoft has cut its target date for delivering a scalable, practical quantum computer in half, now aiming for 2029. This revised goal suggests a faster path toward commercially viable quantum computing capabilities.
