Multiparameter cascaded quantum interferometer
Baihong Li, Qi-qi Li, Zhuo-zhuo Wang +5
We theoretically propose a multiparameter cascaded quantum interferometer in which a two-input and two-output setup is obtained by concatenating 50:50 beam splitters with indep…

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…
