Practical, High-Speed, Gaussian Modulated Coherent State Continuous Variable Quantum Key Distribution with Real-Time Post Processing
Quantum key distribution is proven to achieve unconditional security based on the laws of quantum physics. Quantum key distribution was originally proposed using discrete variables. Later, continuous-variable quantum key distribution has been introduced. Continuous variable quantum key distribution …
