High speed quantum key distribution system
WebTo conclude, we have demonstrated a quantum key distribution system that relies on readily available coherent states, continuous variable measurements and post selection to generate a shared key between Alice and Bob. The states are polarization encoded, ensuring fast modulation, and perfect mode overlap in Bob’s homodyne detector.
