# Symmetric extendibility for a class of qudit states

@article{Ranade2009SymmetricEF, title={Symmetric extendibility for a class of qudit states}, author={Kedar S. Ranade}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2009}, volume={42}, pages={425302} }

The concept of symmetric extendibility has recently drawn attention in the context of tolerable error rates in quantum cryptography, where it can be used to decide whether quantum states shared between two parties can be purified by means of entanglement purification with one-way classical communication only. Unfortunately, at present there exists no simple general criterion to decide whether a state possesses a symmetric extension or not. In this paper, we derive criteria for symmetric…

The goal is to find the highest value of the quantum bit-error rate (QBER) Q for which two-way classical post-processing protocols on the data can distill secret keys and results appear to indicate that they are not.
