PsiQuantum said on Wednesday it had cracked one of the crucial challenges in quantum computing: a method to manufacture quantum chips at the volumes needed to build commercially viable machines. Quantum technology has the potential to perform types of calculations that would stump even the most powerful artificial intelligence systems that use Nvidia chips and could unlock a host of scientific and commercial applications,

There isn't yet a roadmap to show Microsoft can scale its chip to the million topological qubits required to make a working quantum computer.

Microsoft on Wednesday announced Majorana 1, its first quantum computing chip. The achievement comes after the company has spent nearly two decades of research in the field.
