The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency ...
Vibrational sum-frequency generation (VSFG) is a nonlinear spectroscopic method widely used to investigate the molecular structure and dynamics of surface systems. However, in far-field observations, ...

Entanglement swapping using sum-frequency generation between single photons demonstrated for first time
To overcome this limitation, a theoretical scheme based on entanglement swapping using sum-frequency generation (SFG) between single photons has been proposed. In this approach, by detecting the ...
a When photon-pair generation is probabilistic, a two-photon interference measurement between A2 and B1 alone cannot distinguish successful events from unsuccessful ones. Therefore, additional ...
