Ultra-long distance and efficient entanglement distribution over 200 kilometers

Not Accessible

Your library or personal account may give you access

Abstract

Entanglement distribution over 200 kilometers of optical fiber is demonstrated with practical, low-cost, InGaAs avalanche photodiodes. High coincidence count rates are also observed indicating entangled based quantum key distribution is feasible over ultra-long distances.
