Abstract
Quantum dots provide a bright source of single photons with high purity and indistinguishability, bringing them into integrated sources for quantum photonics. Integration of these quantum emitters with nanophotonic structures enables efficient generation and manipulation of single photons. In particular, photonic crystal devices enable high Purcell effect, high coupling efficiency, and strong nonlinearity. These abilities enable quantum dots to be useful for several applications in quantum information processing such as quantum teleportation, quantum simulation, and quantum logic gate. Nevertheless, to date, there exist only few results on multiple quantum dots on nanophotonic structures, while most applications in quantum information processing require multiple, identical quantum emitters generating indistinguishable single photons. A major problem is a spectral randomness in self-assembled quantum dots, and the fabrication errors cause additional randomness in the optical modes of nanophotonic devices. Therefore, scalable quantum photonic devices require a new method for integrating multiple quantum dots with photonic structures on a single chip. In this talk, we present the integration of multiple quantum dots with individual photonic crystal cavities and waveguides and report quantum interference from chip-integrated multiple quantum dots[1,2]. Also we demonstrate hybrid integration of quantum emitters with Si photonic chip, enabling integrated quantum photonics[3]. These approaches pave the way for large-scale quantum photonics with integrated quantum emitters
