I'm on that project myself, we are also dealing with simulating circuits, buuut I feel like we could improve our approach somewhat lol. For example, we had a bunch of trouble trying to speed things up, I immediately thought of trying to make most things run on a GPU but we quickly found out that our circuits just have too few qubits to be parallelized decently.
More importantly, I am not very optimistic (to say the least) about the short- to medium-term real-world applications of quantum circuits we are looking into (we do time series classification, which is quite removed from other domains which work better on these computers), and I got the same feeling from the literature. Should I be feeling differently?
