In this talk, I will report our recent implementation of squeezed vacuum states at 1064 nm. With a bow-tie, optical parametric oscillator (OPO) cavity, and our home-made balanced homodyne detectors, noise reduction up to 10dB below the vacuum is measured. Applications of our squeezer to the gravitational wave detection will be discussed, with the collaboration with Japanese KAGRA project. At the same time, based on the niche of silicon photonics technologies and semiconductor industries in Taiwan, we will also introduce our new project toward the implementation of scalable quantum photonic chips by integrating photonic qubits (single photon source, entangled photon pair, squeezed light), optical components based on silicon photonics, and photon detector arrays (single photon avalanche diode, homodyne detector).
