Data post-processing for the one-way heterodyne protocol under composable finite-size security

  title={Data post-processing for the one-way heterodyne protocol under composable finite-size security},
  author={Alexander G. Mountogiannakis and Panagiotis Papanastasiou and Stefano Pirandola},
The performance of a practical continuous-variable (CV) quantum key distribution (QKD) protocol depends significantly, apart from the loss and noise of the quantum channel, on the postprocessing steps which lead to the extraction of the final secret key. A critical step is the reconciliation process, especially when one assumes finite-size effects in a composable framework. Here, we focus on the Gaussian-modulated coherent-state protocol with heterodyne detection in a high signal-to-noise ratio…

We extend the asymptotic security of continuous variable quantum key distribution using one-way and two-way quantum communication to a multi-way setting: Quantum signals travel many times between the


Composably secure data processing for Gaussian-modulated continuous-variable quantum key distribution
A Gaussian-modulated coherent-state protocol with homodyne detection in the general setting of composable finite-size security and the high signal-to-noise regime which requires the use of high-rate (non-binary) low-density parity check codes is analyzed.
