Quantum computation solves a half-century-old enigma: Elusive vibrational states of magnesium dimer found.

abstract：:We propose a method to use artificial neural networks to approximate light scattering by multilayer nanoparticles. We find that the network needs to be trained on only a small sampling of the data to approximate the simulation to high precision. Once the neural network is trained, it can simulate such optical processe...
