Improving Eight-State Continuous Variable Quantum Key Distribution by Applying Photon Subtraction
We propose a new method to effectively improve the performance of a quantum key distribution with eight-state continuous variables by the photon subtraction method. This operation is effective in increasing and distilling Gaussian entanglement between quantum states, and can be easily realized by ex...
