Learning Coulomb Diamonds in Large Quantum Dot Arrays

We introduce an algorithm that is able to find the facets of Coulomb diamonds in quantum dot arrays. simulate these arrays using constant-interaction model, and rely only on one-dimensional raster scans (rays) learn a model device regularized maximum likelihood estimation. This allows us determine, for given charge state device, which transitions exist what compensated gate voltages are. For smaller devices simulator can also be used compute exact boundaries diamonds, we use assess our correctly finds vast majority with high precision.
