Abstract

Quantum secret sharing (QSS) is an important branch of secure multiparty quantum computation. Several schemes for (n,n)(n, n) threshold QSS based on quantum Fourier transformation (QFT) have been proposed. Inspired by the flexibility of (t,n)(t, n) threshold schemes, Song {\it et al.} (Scientific Reports, 2017) have proposed a (t,n)(t, n) threshold QSS utilizing QFTQFT. Later, Kao and Hwang (arXiv:1803.00216) have identified a loophole in the scheme but have not suggested any remedy. In this present study, we have proposed a (t,n)(t, n) threshold QSS scheme to share a dd dimensional classical secret. This scheme can be implemented using local operations (such as QFTQFT, generalized Pauli operators and local measurement) and classical communication. Security of the proposed scheme is described against outsider and participants' eavesdropping.
