Abstract

Recently, Modi et al. [Phys. Rev. Lett. 120, 230501 (2018)] found that masking quantum information is impossible in a bipartite scenario. This adds another item to the no-go theorems. In this paper, we present some schemes different from error correction codes, which show that quantum states can be masked when more participants are allowed in the masking process. Moreover, using a pair of mutually orthogonal Latin squares of dimension d, we show that all the d level quantum states can be masked into tripartite quantum systems whose local dimensions are d or d+1. This highlights some differences between the no-masking theorem and the classical no-cloning theorem or no-deleting theorem.
