Description
We revisited the sphaleron configuration in a 1+1-dimensional (1+1D) field theory model, achieved by introducing linear additional terms into the action of the $O(3)$ nonlinear $\sigma$-model. We discretize the Lagrangian of the aforementioned 1+1D model and construct a Hamiltonian representation based on unitary quantum gate forms, enabling the construction of quantum-simulated sphaleron. Subsequently, we devise a sophisticated adiabatic simulation method based on the field space properties of quantum-bits and the corresponding structure of the model field, obtaining the quantum-simulated 1D sphaleron states.
