TLDR
In this article, a scheme for quantum state sharing of an arbitrary multiqubit state using nonmaximally entangled GHZ states as the quantum channel and generalized Bell states as measurement basis is presented.Abstract:
We explicitly present a scheme for quantum state sharing of an arbitrary multiqubit state using nonmaximally entangled GHZ states as the quantum channel and generalized Bell states as the measurement basis. The scheme succeeds only probabilistically with its total success probability depending on the degree of entanglement matching between the quantum channel and the generalized Bell states. Security of the scheme is guaranteed by the fact that attacks of an outside eavesdropper or/and an inside dishonest party will inevitably introduce detectable errors.read more

Optimizing resource consumption, operation complexity and efficiency in quantum-state sharing
TL;DR: In this paper, a tripartite scheme for securely sharing an arbitrary two-qubit quantum information (i.e., a quantum state) is shown. And the optimal scheme has the distinct advantages of consuming fewer quantum and classical resources, lessening the difficulty and intensity of necessary operations, and having higher intrinsic efficiency.

Controlled Teleportation Using Four-Particle Cluster State
TL;DR: A controlled teleportation scheme is presented which transfers quantum information of a single-qubit state or an entangled two-qubits state through a four-particle cluster state under the control of the supervisor.

Bidirectional Quantum Controlled Teleportation via a Maximally Seven-qubit Entangled State
TL;DR: In this paper, a bidirectional quantum controlled teleportation scheme using a seven-qubit maximally entangled state as quantum channel is proposed, where Alice can transmit an arbitrary single qubit state of qubit a to Bob and Bob can transmit a single qubits to Alice via the control of the supervisor Charlie.

Multiparty quantum secret sharing based on Bell measurement
TL;DR: In this multiparty quantum secret sharing scheme, all agents are not required to prepare entangled states or perform any local unitary operation, and the total efficiency of the scheme approaches to 100%.

How to share a secret
TL;DR: This technique enables the construction of robust key management schemes for cryptographic systems that can function securely and reliably even when misfortunes destroy half the pieces and security breaches expose all but one of the remaining pieces.

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?
TL;DR: Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that one is led to conclude that the description of reality as given by a wave function is not complete.

Quantum secret sharing
TL;DR: This work shows how GHZ states can be used to split quantum information into two parts so that both parts are necessary to reconstruct the original qubit.

How to share a quantum secret
TL;DR: The concept of quantum secret sharing was investigated in this article, where it was shown that the only constraint on the existence of threshold schemes comes from the quantum ''no-cloning theorem''.

Quantum entanglement for secret sharing and secret splitting
TL;DR: In this article, a two-particle quantum entanglement protocol for secret sharing and splitting was proposed. But the secrecy sharing protocol must be carefully designed in order to detect eavesdropping or a dishonest participant.
