Computational Quantum Secret Sharing [PDF]
CoRR, 2023 Quantum secret sharing (QSS) allows a dealer to distribute a secret quantum state among a set of parties so that certain subsets can reconstruct the secret, while unauthorized subsets obtain no information. While QSS was introduced over twenty years ago, previous works focused only on existence of perfectly secure schemes, and the share size of the ...

Advance Sharing of Quantum Shares for Classical Secrets
IEEE Access, 2022 Secret sharing schemes for classical secrets can be classified into classical secret sharing schemes and quantum secret sharing schemes. Classical secret sharing has been known to be able to distribute some shares before a given secret. On the other hand,

Is quantum secret sharing different to the sharing of a quantum secret? [PDF]
SPIE Proceedings, 2004 We present an experimental scheme to perform continuous variable (2,3) threshold quantum secret sharing on the quadratures amplitudes of bright light beams. It requires a pair of entangled light beams and an electro-optic feedforward loop for the reconstruction of the secret.

Quantum Teleportation of Shared Quantum Secret [PDF]
Physical Review Letters, 2020 Quantum teleportation allows to transfer unknown quantum states between distant parties. It is not only a primitive of quantum communications but also an essential task in realization of the quantum networks for promising applications such as quantum cryptography and distributed quantum computation.
