To entangle independent photons of different color, researchers use down-conversion to generate two pairs of polarization-entangled photons, labeled (A, a) and (B, b). The frequencies of each pair differ by either 40 or 80 MHz. Photons a and b enter a beam splitter, resulting in a “hypoentangled” state of polarization and frequency.
