Multilevel Quantum Secret Sharing

, 2011
[[abstract]]We use quantum mechanics to handle our information，such as Quantum Cryptography。Quantum Cryptography can send information and keep the transmission secret by using uncertainty principal and entanglement between particles。 We can divide ...

Secret sharing with a single d-level quantum system

, 2015
We give an example of a wide class of problems for which quantum-information protocols based on multisystem entanglement can be mapped into much simpler ones involving one system.

Dynamic hierarchical quantum secret sharing protocol based on high-dimensional GHZ state

网络与信息安全学报
Quantum secret sharing is an important research branch of quantum cryptography. A novel dynamic hierarchical quantum secret sharing protocol based on high-dimensional GHZ (Greenberger-Horne-Zeilinger) state was proposed.

Reviving a Grover based Quantum Secret Sharing Scheme [PDF]

Secret-sharing schemes allow a dealer to split a secret into multiple “shares” and distribute them individually among many parties while mandating certain constraints on its reconstruction.

Progress and prospect of quantum secret sharing

网络与信息安全学报
In quantum secret sharing (QSS), secret information was encoded onto quantum states by a secret distributor and distributed to participants, where decoding could only be achieved through cooperative efforts. Based on the fundamental principles of quantum
