I wrote an overview of the current SOTA in qubit count, quality qubits, fidelity and gate times across the 5 main qubit modalities.

In my view, neutral atoms are the current and nascent leader. A friend told me that publications for neutral atoms have recently surpassed superconducting qubits and trapped ions.

Please let me know if you have any corrections or comments, thanks for reading!
