Quantum computing holds the potential to revolutionize fields such as cryptography, optimization, and quantum simulations. Among various quantum computing approaches, optical quantum computers are particularly promising due to their high-speed operations, scalability, and compatibility with communication technologies [1]. Recent advances in time-domain multiplexing have demonstrated the proof of principle of large-scale analog quantum computation in optical setups [2], [3]. However, previous systems have been limited by the number of inputs, clock frequency, and flexibility.
