520 _ _ |a The advancement of quantum computing encounters a significant hurdle in the form of undesirable stray couplings. These couplings have the potential to impede gate operations and lead to fidelity loss. In this talk, we delve into an investigation of the influence of stray couplings within a multiqubit circuit. We introduce analytical expressions to quantitatively measure these effects, highlighting the essential parameters to mitigate their parasitic impact. We also reveal the feasibility of completely suppressing all stray interactions. Furthermore, our research explores the exciting prospect of achieving multiqubit capabilities surpassing those of traditional two-body interactions. This breakthrough holds promise for enhancing the optimization and overall performance of quantum algorithms.
