Pathways for Entanglement-Based Quantum Communication in the Face of High Noise
Pathways for Entanglement-Based Quantum Communication in the Face of High Noise
Entanglement-based quantum communication offers an increased level of security in practical secret shared key distribution. One of the fundamental principles enabling this security---the fact that interfering with one photon will destroy entanglement and thus be detectable---is also the greatest obstacle. Random encounters of traveling photons, losses, and technical imperfections make …
