Quantum metrology timing limits of biphoton frequency comb
Baihong Li, Qi-qi Li, Boxin Yuan +3
Biphoton frequency comb (BFC), which encompasses multiple discrete frequency modes and represents high-dimensional frequency entanglement, is crucial in quantum information process…
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…
Energy-time entanglement and intermediate state dynamics in two photon absorption
Baihong Li, Holger F. Hofmann
It is well known that energy-time entanglement can enhance two photon absorption (TPA) by simultaneously optimizing the two photon resonance and the coincidence rate of photons at…
Nonlocality test of energy-time entanglement via nonlocal dispersion cancellation with nonlocal detection
Baihong Li, Feiyan Hou, Runai Quan +6
Energy-time entangled biphoton source plays a great role in quantum communication, quantum metrology and quantum cryptography due to its strong temporal correlation and capability…
Fiber-Optic quantum two-way time transfer with frequency entangled pulses
Feiyan Hou, Runai Quan, Ruifang Dong +8
High-precision time transfer is of fundamental interest in physics and metrology. Quantum time transfer technologies that use frequency-entangled pulses and their coincidence detec…
