Development of biphoton entangled light spectroscopy (BELS) using Bell pairs

We introduce Biphoton Entangled Light Spectroscopy (BELS), a quantum spectroscopic technique that employs polarization-entangled Bell pairs and two-photon interference to probe material properties. In BELS, the measured signal arises not from single-photon intensities but from ch...
