- Abstract: Unintended interactions between qubits, known as stray couplings, negatively
impact gate operations, leading to errors. This study highlights the
significance of incorporating the lattice Hamiltonian into quantum circuit
design. By comparing the intensity of three-body versus two-body stray
couplings, we identify non-trivial circuit parameter domains that help to
enhance fidelity of two-qubit gates. Additionally, we demonstrate instances
where three-body ZZZ interactions surpass two-body ZZ interactions within the
parameter space relevant to quantum computing, indicating the potential use of
lattice Hamiltonian for designing novel multi-qubit gates essential for
advancing quantum computing technologies.
