We invented the scheme of teleportation-based quantum computing in 2013 [1]. In this scheme, we can multiplex quantum information in the time domain and we can build a large-scale optical quantum computer only with four squeezers, five-six beam splitters, and two optical delay lines [2]. We built a real machine of optical quantum computer in Riken and put it on the cloud [3]. We will work on a neural network and Shor’s algorithm with the real machine.
