报告摘要/Abstract：In this presentation, I will firstly introduce the background of quantum emission based on cavity QED and its applications. Then, I mainly introduce our recent works regarding multi-photon/phonon bundle emission theory with electron-phonon and Rabi interactions. Specifically, we propose the optical heralded multi-phonon bundle emission and parity-symmetry-protected multiphoton emission. Our works broaden the realms of multi-quanta physics, with potential applications for on-chip quantum information processing, quantum metrology, and engineering of new types of quantum devices, such as optically heralded n-phonon guns, symmetry protected n-photon laser.
