Quantum-to-the-Home: Achieving Gbits/s Secure Key Rates via Commercial Off-the-Shelf Telecommunication Equipment

Figure 4

Calculated QKD secure key rates as a function of transmission distance for (a) 4-PSK and 8-PSK modulation and (b) single-channel (1-Ch) 4-PSK modulation and 12-channel WDM 4-PSK modulation with 25 and 50 GHz channel spacing. Simulations are performed by assuming 60 detector efficiency and 95 reconciliation efficiency.
