Abstract A high-dimensional generalized wave function probability distribution reconstruction model is proposed in this paper to investigate the generalization performance of the ground-state wave functions in the reconstructed high-qubit transverse-field Ising model. By leveraging the autoregressive properties of Mamba and combining them with an efficient sampling process, independent training samples can be automatically generated without the need for additional labeled samples. By combining multi-ground-state scaling with the variational Monte Carlo optimization strategy, the model trains the weights of the high-qubit universal wave function using only a small number of different physical parameters within a limited range. In numerical simulation experiments of wave function reconstruction for a 40-qubit system, the model weights are trained using only partial values of external field strength ranging from 0.5 to 1.5, and the model achieves high-precision universal wave function reconstruction of quantum state families with external field strengths ranging from 0 to 2. In numerical simulation experiments of wave function reconstruction for systems with qubits ranging from 40 to 80, the proposed model exhibits better generalization ability and more efficient inference performance, providing an efficient and accurate generalized reconstruction method for the ground-state probability distribution of high-qubit systems.
