Quantum Secret Sharing Scheme

A high-capacity quantum secret sharing scheme based on orbital angular momentum is proposed. The dealer uses single particles in the orbital angular momentum (OAM) basis to bring the secret and encodes the secret through performing the transformation between the orbital angular momentum (OAM) basis and the angular position (ANG) basis. In the recovery, the participants perform the single-particle measurements to reconstruct the secret. The proposed scheme can use the multi-dimension of OAM to reach higher information capacity and enhanced security.

Quantum Secret Sharing Scheme

A three-party quantum secret sharing scheme is proposed, in which the dealer uses the d-dimensional Bell state to distribute the secret, the participants perform the single-particle measurements to get their shares, and the dealer performs the Bell-basis measurements to check the eavesdropping. The main merit of our scheme is that the participants only need to measure the particles in one basis. Compared to the existing schemes in which the participants need to measure the particles in two bases, our scheme will be more practical.

Quantum Secret Sharing Scheme

Based on an orthogonal set of product states of two three-state particles, a new quantum secret sharing scheme is proposed, which uses a novel distribution strategy so that continuous and independent measurements, rather than particle-wise coordinated ones, are performed. As a result, it is convenient and efficient to implement. The scheme is also secure against several common attacks and gets rid of partial-information leakage due to the revised coding method. Moreover, the quantitative analysis shows that the security can be further improved by using more product states from appropriate multiple sets.

Quantum Secret Sharing Scheme

A recent paper proposed a semi-quantum secret sharing (SQSS) scheme based on Bell states [A. Yin et al., Mod. Phys. Lett. B. https://doi.org/10.1142/S0217984917501500 ]. This protocol was presumed that only the sender has the quantum power and all participants perform classical operations. However, we find this protocol is not that secure as it is expected. We can utilize the intercept-resend method to attack this scheme. Then, we give an improvement strategy based on semi-quantum key distribution, which ensures that the new scheme resists the attack we have proposed.
