Experimental Test of Two-Way Quantum Key Distribution in the Presence of Controlled Noise
Alessandro Ceré, Marco Lucamarini, Giovanni Di Giuseppe, Paolo Tombesi · Physical Review Letters · 2006
We describe the experimental test of a quantum key distribution performed with a two-way protocol without using entanglement. An individual incoherent eavesdropping is simulated and induces a variable amount of noise on the communication channel. This allows a direct verification of the agreement between theory and practice.
