    • This also holds for other degrees of freedom causing mode, frequency, or time-energy entanglement. The generic effect also leads to entanglement between a higher number of photons. Interferometrically enhanced down-conversion [9] may allow access to states with more than four photons in the future.

    • For this reason, a particular type of state [Eq. (1)] can be used for decoherence-free communication [11].
