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…
Dynamic temperature compensation for wavelength-stable entangled biphoton generation
Yuting Liu, Huibo Hong, Xiao Xiang +5
A dynamic temperature compensation method is presented to stabilize the wavelength of the entangled biphoton source, which is generated via the spontaneous parametric down-conversi…
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…
Quantum two-way time transfer over a 103 km urban fiber
Huibo Hong, Runai Quan, Xiao Xiang +5
As a new approach to realizing high-precision time synchronization between remote time scales, quantum two-way time transfer via laboratory fiber link has shown significant enhance…
Quantum two-way time transfer over a hybrid free-space and fiber link
Xiao Xiang, Bingke Shi, Runai Quan +9
As the superiority of quantum two-way time transfer (Q-TWTT) has been proved convincingly over fiber links, its implementation on free-space links becomes an urgent need for remote…
