Continuous variable quantum key distribution with modulated entangled states [PDF]
Nature Communications, 2012 Quantum key distribution enables two remote parties to grow a shared key, which they can use for unconditionally secure communication over a certain distance. The maximal distance depends on the loss and the excess noise of the connecting quantum channel.

Self-Referenced Continuous-Variable Quantum Key Distribution Protocol [PDF]
Physical Review X, 2015 We introduce a new continuous-variable quantum key distribution (CV-QKD) protocol, self-referenced CV-QKD, that eliminates the need for transmission of a high-power local oscillator between the communicating parties.

Enhancing of Self-Referenced Continuous-Variable Quantum Key Distribution with Virtual Photon Subtraction [PDF]
Entropy, 2018 The scheme of the self-referenced continuous-variable quantum key distribution (SR CV-QKD) has been experimentally demonstrated. However, because of the finite dynamics of Alice’s amplitude modulator, there will be an extra excess noise that is ...

Parameter Optimization Based BPNN of Atmosphere Continuous-Variable Quantum Key Distribution [PDF]
Entropy, 2019 The goal of continuous variable quantum key distribution (CVQKD) is to be diffusely used and adopted in diverse scenarios, so the adhibition of atmospheric channel will play a crucial part in constituting global secure quantum communications. Atmospheric

SecurityBounds for Continuous Variables Quantum Key Distribution [PDF]
Physical Review Letters, 2005 Security bounds for key distribution protocols using coherent and squeezed states and homodyne measurements are presented. These bounds refer to (i) general attacks and (ii) collective attacks where Eve interacts individually with the sent states, but delays her measurement until the end of the reconciliation process.
