This question is regarding the simulation of qubits, using FPGAs. My question is: how does using FPGAs to simulate qubits help us understand or give us an insight into how quantum computers could be constructed? I know many quantum computation scientists use software to simulated qubits, for example, Matlab and even Python. But I just don't understand why to use FPGAs. I know for a fact that FPGAs are really useful in speeding up processing power and execute processes in parallel.
Is this the sole purpose of using FPGAs or are there other reasons why they are being used in quantum computation simulations?
