Research Abstract

We developed elemental technology for optical integration of quantum teleportation circuits which are utilizing squeezed state of light. It is important to develop a technology for operating waveguide devices for optical integration.We succeeded in generating continuous-wave squeezed light by using waveguide squeezer. We also succeeded in generating EPR beams and verifying quantum entanglement by utilizing waveguide beam-splitter.
