Achieving precise control over quantum systems presents a significant challenge, especially in many-body setups, where residual couplings and unintended transitions undermine the accuracy of quantum operations. In superconducting qubits, parasitic interactions—both between distant qubits and with sp… [Phys. Rev. Lett. 135, 160804] Published Tue Oct 14, 2025
