While the single-qubit operations are already quite reliable, with a fidelity above 99%, a crucial next step would be to show ...

This result complements then-MIT researcher Leon Ding's demonstration last year of a 99.92% two-qubit gate fidelity. The findings are published in the journal PRX Quantum. The paper's senior ...

This includes a new cryogenic hardware design to reduce the amount of metal at the refrigerator’s coldest stage, increasing efficiency and reducing the cost per qubit, and an improved qubit chip ...
