Long Distance Continuous-Variable Quantum Key Distribution with a Gaussian Modulation
We designed high-efficiency error correcting codes allowing to extract an errorless secret key in a Continuous-Variable Quantum Key Distribution (CVQKD) protocol using a Gaussian modulation of coherent states and a homodyne detection. These codes are available for a wide range of signalto-noise ratios on an Additive White Gaussian Noise Channel (AWGNC) with a binary modulation and can be combin...
متن کاملLong-Distance Continuous-Variable Quantum Key Distribution with Advanced Reconciliation of a Gaussian Modulation
The two-way continuous-variable quantum key distribution (CVQKD) systems allow higher key rates and improved transmission distances over standard telecommunication networks in comparison to the one-way CVQKD protocols. To exploit the real potential of two-way CVQKD systems a robust reconciliation technique is needed. It is currently unavailable, which makes it impossible to reach the real perfo...
متن کاملContinuous-variable quantum enigma machines for long-distance key distribution
Quantum physics allows for unconditionally secure communication through insecure communication channels. The achievable rates of quantum-secured communication are fundamentally limited by the laws of quantum physics and in particular by the properties of entanglement. For a lossy communication line, this implies that the secret-key generation rate vanishes at least exponentially with the commun...
متن کاملUnconditional security proof of long-distance continuous-variable quantum key distribution with discrete modulation.
We present a continuous-variable quantum key distribution protocol combining a discrete modulation and reverse reconciliation. This protocol is proven unconditionally secure and allows the distribution of secret keys over long distances, thanks to a reverse reconciliation scheme efficient at very low signal-to-noise ratio.
متن کاملQuantum Key Distribution using Continuous-variable non-Gaussian States
In this work we present a quantum key distribution protocol using continuous-variable nonGaussian states, homodyne detection and post-selection. The employed signal states are the Photon Added then Subtracted Coherent States (PASCS) in which one photon is added and subsequently one photon is subtracted. We analyze the performance of our protocol, compared to a coherent state based protocol, for...
