Stochastic reconfiguration (SR) is a method to enhance the optimization of variational functions in quantum many-body systems but becomes impractical beyond a few thousand parameters. Here, the authors combine an alternative SR formulation with a Deep Transformer architecture with 105 parameters, achieving the best variational energy for the J1–J2 Heisenberg model on the 10 × 10 square lattice
