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?

    $\begingroup$ Where have your heard or read that we use FPGA's to simulate qubits? Please provide a reference. I've been in the field for a while and haven't heard of simulating qubits on an FPGA, so I'm puzzled by this question. $\endgroup$ – DanielSank Nov 22 '18 at 18:38
  • $\begingroup$ @DanielSank Lookup these papers: 1.) FPGA Emulation of Quantum Circuits by Ahmed Usman Khalid 2.) FPGA Quantum Computing Emulator Using High Level Design Tools by Agustin Silva and Omar Gustavo Zabaleta 3.) A space-efficient quantum computer simulator suitable for high-speed FPGA implementation by Michael P. Frank, Liviu Oniciuc, Uwe H.Meyer-Baese, Irinel Chiorescu. These are some of the papers that I have come across that talk about this. Like I said before, I don’t fully understand the benefit of doing this, the only reason I could see why would the speed-up of simulations. $\endgroup$ – alfonso guevara Nov 24 '18 at 5:27
