Security of continuous-variable quantum cryptography with Gaussian postselection
We extend the security analysis of continuous variable quantum-key- distribution protocols using a family of post selection schemes to account for arbitrary eavesdropping attacks. We show that the postselection protocol is equivalent to a virtual entanglement-based protocol including a distillation stage. We introduce a particular 'Gaussian' post selection and demonstrate that the security can be calculated using only experimentally accessible quantities. Finally, we explicitly evaluate the...[Show more]
