In the field of continuous-variable quantum information processing, the development of elemental technologies such as implementing large-scale quantum processors and generating quantum states in the tens of GHz bandwidth is progressing. Integrating these technologies requires system switching and control via optical switches. However, conventional interferometer-based optical switches are limited to kHz order repetition frequencies. Therefore, this research proposes and aims to demonstrate a new low-loss, high-repetition-rate optical switching mechanism using selective quantum teleportation. In this presentation, we will report on the teleportation circuit's evaluation and the system's construction and evaluation for generating Schrödinger's cat states as the input states.
