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. Quant

Microsoft on Wednesday unveiled a new chip that it said showed quantum computing is "years, not decades" away, joining Google and IBM in predicting that a fundamental change in computing technology is much closer than recently believed.

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.
