Microsoft's Majorana 2 quantum chip is 1,000x more reliable, targets 2029
Microsoft unveiled Majorana 2, a quantum chip with qubits 1,000x more reliable than its predecessor, achieving a mean 20-second lifetime versus microseconds for competitors. Agentic AI via Microsoft Discovery accelerated the development, and Microsoft now targets a scalable quantum computer by 2029, halving its original timeline.

TL;DR
- Microsoft's Majorana 2 quantum chip features qubits 1,000 times more reliable than the first Majorana chip.
- Qubit lifetimes have increased to a mean of 20 seconds, compared to microseconds for competing approaches.
- Agentic AI, through the Microsoft Discovery platform, accelerated materials science, fabrication optimization, and measurement automation.
- Microsoft has cut its target for a scalable quantum computer from 2033 to 2029.
- The chip uses lead as a superconductor, offering natural shielding from cosmic disturbances.
- Microsoft Discovery platform is now generally available for organizations to deploy AI agent teams for R&D.
- The quantum computing sector is experiencing significant funding and IPO activity.
