Microsoft presents its new Majorana 2 quantum chip, with qubits 1,000 times more reliable
Microsoft has presented its new quantum chip, Majorana 2, which is 1,000 times more reliable than its first version, presented in February 2025. The company has announced that the material architecture of this chip multiplies the reliability of its qubits, the minimum unit of information in a quantum computer, by 1,000. The qubits of Majorana 2 have an average lifetime of 20 seconds and peaks reaching one minute compared to the microseconds of conventional quantum chips. After the chip presentation, the company sets its goal to build a scalable quantum computer by 2029, halving the initial target timeline.
