ZZ freedom in two qubit gates
Xuexin Xu, M. H. Ansari
Superconducting qubits on a circuit exhibit an always-on state-dependent phase error. This error is due to sub-MHz parasitic interaction that repels computational levels from non-c…

Suppression of Unwanted Interactions in a Hybrid Two-Qubit System
Jaseung Ku, Xuexin Xu, Markus Brink +4
Mitigating crosstalk errors, whether classical or quantum mechanical, is critically important for achieving high-fidelity entangling gates in multi-qubit circuits. For weakly anhar…
