Generation of continuous-wave highly squeezed light with optical parametric amplifier in waveguide

我们发展了利用光的压缩态的量子隐形传态电路的光学集成的基本技术。利用光波导压缩器成功地产生了连续波压缩光，并在光波导器件中实现了连续波压缩。利用波导分束器成功地产生了EPR光束并验证了量子纠缠。

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.
