Distribution of polarization-entangled photon pairs to remote users changes the degree of their entanglement in captivating ways. We will describe bounds to the reach of potential entanglement-based quantum cryptography systems arising from Polarization Mode Dispersion.

Using a low-loss optical storage loop and polarization entangled photons, we demonstrate a quantum cryptography protocol in which the sifting step is eliminated and every photon may contribute to the final key.
