Scaling Quantum Scattering Calculations with a Novel Iterative Method
![The computational scaling of the WISE algorithm reveals a performance trade-off: while total solution time and the identification of divergent Weinberg eigenvalues scale quadratically with the number of scattering channels [latex] \propto N^{2} [/latex], convergence of the Born series for both the regularized source vector and eigenvectors achieves linear scaling [latex] \propto N [/latex], suggesting a fundamental limit to efficiency as system complexity increases.](https://arxiv.org/html/2601.01159v1/x4.png)
Researchers have developed a new algorithm that dramatically improves the efficiency of quantum scattering calculations, potentially unlocking simulations of more complex molecular collisions.
