Device-independent quantum key distribution (DI-QKD) represents one of the most fascinating challenges in quantum communication, exploiting concepts of fundamental physics, namely Bell tests of nonlocality, to ensure the security of a communication link. This requires the loop ...
We experimentally studied heralded photon amplification for path entangled states and characterise entanglement before and after loss by exploiting displacement-based measurements. We demonstrate the recovery of high fidelity entangled states over lossequivalent distances > 50km.
