# Quantum multipartite maskers vs. quantum error-correcting codes

@article{Han2020QuantumMM, title={Quantum multipartite maskers vs. quantum error-correcting codes}, author={Kanyuan Han and Z. H. Guo and H. X. Cao and Yu Du and C. Yang}, journal={Europhysics Letters}, year={2020}, volume={131} }

Since masking of quantum information was introduced by Modi et al. in Modi K. et al., Phys. Rev. Lett., 120 (2018) 230501, many discussions on this topic have been published. In this paper, we explore the relationship between quantum multipartite maskers (QMMs) and quantum error-correcting codes (QECCs). We say that a subset Q of pure states of a system can be masked by an operator S into a multipartite system if all of the image states of states in Q have the same marginal states on each…
