主 题：quantum multiphoton realization
摘 要：Multiphoton quantum states play a critical role in emerging quantum technologies and greatly improve our fundamental understanding of the quantum *** photonics is well recognized as an attractive technology offering great promise for the generation of photonic quantum states with high-brightness,tunability,stability,and ***,we demonstrate the generation of multiphoton quantum states using a single-silicon nanophotonic *** detected four-photon rate reaches 0.34 Hz even with a low-pump power of 600μ*** multiphoton quantum state is also qualified with multiphoton quantum interference,as well as quantum state *** the generated four-photon states,the quantum interference visibilities are greater than 95%,and the fidelity is 0.78±***,such a multiphoton quantum source is fully compatible with the on-chip processes of quantum manipulation,as well as quantum detection,which is helpful for the realization of large-scale quantum photonic integrated circuits(QPICs)and shows great potential for research in the area of multiphoton quantum science.
