Abstract

Photon-photon interaction is a crucial element in the development of quantum information science and engineering. We developed an InGaP quantum photonic platform with an extreme χ(2) nonlinearity combined with low optical losses in the near infrared wavelength range. Based on the InGaP quantum photonic platform, we realized direct photon-photon interactions via bulk optical nonlinearity, leading to exotic quantum correlations between photons, such as photon repulsion, attraction, and tunneling. This breakthrough opens up exciting possibilities for nonlinear quantum information processing in integrated photonic platforms. We also use the InGaP photonic devices for nonlinearity-enabled quantum networking, including sum-frequency generation enabled quantum teleportation of photons with different wavelengths.
