摘要：
On-chip manipulation of single photons generated deterministically from prespecified sources to create multiphoton entangled states in a scalable platform is a major milestone to be reached in photonic quantum information sciences and technology. In this talk, I will present our proposition [1,2], current status and continuing efforts [3,4] to realize such a photonic chip. A new class of high quality ordered spectrally uniform quantum dots based single photon source (SPS) with single photon emission purity >99% [1,3] has been demonstrated. Such SPS array is strategically embedded in co-designed all-dielectric optical resonant metastructures [2,4] whose single Mie-like resonance in the optical regime provides, as a function of spatial location, the needed five basic photon manipulation functions to create controlled on-chip interference and entanglement: enhancement of the SPS emission rate (Purcell enhancement), directional emission (local antenna), state-preserving propagation, beam-splitting, and beam combining. Nonclassical photon states can be generated utilizing our novel platform. I will present our experimental studies and the theoretical analysis and simulation of such SPS and all-dielectric metastructures integrated structure.
