Time-domain multiplexed cluster-state-based optical quantum computing is a promising architecture that enables both scalability and high-speed operation. However, conventional systems have been limited by bandwidth constraints in the state generation setup, resulting in quantum modes with wavepacket durations on the order of several tens of nanoseconds, and clock rates of around 100 MHz. In this presentation, we report the generation and real-time verification of cluster states with a wavepacket duration of approximately 40 ps, and discuss prospects for high-speed optical quantum computing.
