In measurement-based quantum computing (MBQC), a large-scale quantum entanglement known as a cluster state serves as the processor. To achieve fast optical quantum computing, it is essential to encode quantum states in short-duration wave packets and measure them. As a proof-of-concept for ultrafast MBQC, we aim to develop a measurement technology for broadband cluster states. In this presentation, we will explain the theory, plans, and outlook of the experiment.
