A Sky Full of Synthetic Stars: How the Flexibility of Superconducting Qubits Sparks Innovation

The design of a superconducting qubit is flexible, giving scientists and engineers ...
Virtual Z gates are special because they don't physically alter the qudit's state but instead change the phase of the operations. By assuming these gates are perfect, the new method simplifies the GST process, reducing computational costs and data collection needs.

A more efficient way to characterise the performance of quantum systems

This new GST method successfully characterises qudit logic gates with comparable accuracy ...
