Microsoft reported that its Majorana 2 processor achieved topological qubit lifetimes exceeding 20 seconds.

Microsoft's Majorana 2 qubits last 20 seconds vs microseconds for rivals, built with agentic AI. The company now targets a scalable quantum computer by 2029.

At their annual Build Conference, Microsoft announced improvements in its Majorana qubit design that provides a 20 second parity lifetime with a 1000x increase in the switching…
