Quantum light generation and characterization via cascaded single-photon Raman interactions
Abdolreza Pasharavesh, Sai Sreesh Venuturumilli, Michal Bajcsy · 2025
We propose new approaches for manipulating quantum light at the single-photon level through one-way and two-way cascading of single-photon Raman interaction systems. We demonstrate the potential of the two-way cascaded scheme for generating multi-photon quantum light pulses with fidelities and purities approaching unity. In addition, the one-way design allows for a detailed characterization of non-classical light through photon-number-resolving detection with low error margins, surpassing existing multi-photon detection platforms.
