Entanglement Transmission through a Distributed Phase Sensitive Amplifier1

We demonstrate transmission of entangled photons through a χ(3)-based 5-km distributed optical amplifier operated in the low-gain limit to offset loss. No measurable degradation in entanglement quality is observed after the amplifier.
