Full characterization of biphotons with a generalized quantum interferometer
Baihong Li, Changhua Chen, Boxin Yuan +4
Entangled photons (biphotons) in the time-frequency degree of freedom play a crucial role in both foundational physics and advanced quantum technologies. Fully characterizing them…

Complete spectral characterization of biphotons by simultaneously determining its frequency sum and difference in a single quantum interferometer
Baihong Li, Changhua Chen, Boxin Yuan +2
We theoretically propose a novel quantum interferometer in which the NOON state interferometer (NOONI) is combined with the Hong-Ou-Mandel interferometer (HOMI). This interferomete…

Enhancement of broadband entangled two-photon absorption by resonant spectral phase flips
Baihong Li, Holger F. Hofmann
Broadband energy-time entanglement can be used to enhance the rate of two-photon absorption (TPA) by combining a precise two-photon resonance with a very short coincidence time. Be…
