It doesn’t make sense to me. They run a noiseless quantum simulation and get lower AUC scores than their longer quantum circuit.
The noiseless quantum simulation may not have had a sufficient bond dimension. Either than or the noise is a regularization, and they aren’t getting a quantum benefit but more like a dropout boost. A number of those people I know are ostensibly from the sales team. Just sayin.
