Abstract

With GHZ state as a quantum channel,quantum bit secret sharing can be realized after transmitting the information by a classical channel,which is measured by the GHZ state.Based on the above ideas,making full use of the correlation of a six-particle entanglement GHZ state,by a Bell measurement,four single-particle measurements and the corresponding unitary transformation,a four-qubit secret sharing scheme can be achieved.

Scheme of three quantum bit secret sharing based on GHZ state

Liu Yue-qi

With a five-particle entanglement GHZ state as the quantum channel, a quantum secret sharing scheme is proposed, which put through the three-particle teleportation in order to realize the three-quantum secret sharing. The safety of the scheme is analyzed. The scheme makes full use of five particles' relationship of the GHZ-state. It is found that a Bell-basis measurement, three single particle measurement and corresponding unitary transformation are required. Compared with the pertinent literature, it enhances the quantum transmission without increasing the number of particles, and forms a theoretical basis for transmitting more quanta in quantum secret sharing.

Two schemes of multiparty quantum direct secret sharing via a six-particle GHZ state*

Xin-Wei Zha, Ruo-Xu Jiang, Minrui Wang

Abstract In this paper, two new efficient multiparty quantum direct secret sharing schemes are proposed via a six-particle GHZ state and Bell measurements. In the first scheme, based on the theory of security cryptanalysis, the secret message of the sender is directly encoded into the transmitted particles, and all the agents can obtain their information by performing bell measurement on the received particles, and then cooperate to recover the information of the sender. In the second scheme, we define a new secret shared coding method by performing local unitary operations on the transmitted particles, then agents perform Bell measurements on their own particles respectively, and feedback the measurement to the dealer. If the agent’s results are matched with the previous coding method, the protocol will work out. In addition, the proposed two schemes have the following common advantages: the sender can send all prepared particles to the receiver, and can send an arbitrary key to the receiver, rather than a random secret key; the proposed schemes do not need to insert any detection sets to detect eavesdropping and can resist both existing attacks and spoofing attacks by dishonest agents. The sender need not to retain any photons, so the sender’s quantum memory could be omitted here.

Quantum secret sharing of multi-bits by an entangled six-qubit state

Yinxiang Long, Daowen Qiu, Dongyang Long

Since the first quantum secret sharing protocol based on Greenberger–Horne–Zeilinger (GHZ) states was presented by Hillery et al, dozens of quantum secret sharing protocols based on different entangled states (e.g. Bell states, d-level Bell states and GHZ states, etc) and product states have been developed. In this paper, we present a quantum secret sharing protocol, in which the genuinely maximally entangled six-qubit states, which was found recently by Borras et al, are used. An ordinary entangled state such as a Bell state or a GHZ state, etc can be used to share at most only one bit. However, according to our protocol, Alice can share three bits among three parties by a six-qubit state, which shows that our protocol is more efficient than any previous protocol.

MULTIPARTY QUANTUM STATE SHARING OF m-QUBIT STATE

Li Dong, Xiao‐Ming Xiu, Yajun Gao

A scheme for quantum state sharing (QSTS) of a one-particle state is proposed for a three-particle GHZ state utilized as a quantum channel. After the sender (Alice) makes Bell-state measurements (BM) on her particles, and the controller (Charlie) performs a computational basis measurement (CM), the recipient (Bob) only needs to carry out a unitary transformation of the classical information from the sender and the controller. Finally, the scheme is generalized to multiparty QSTS of a one-qubit state with n agents and an m-qubit state with n agents.

Quantum State Sharing of an Arbitrary Single Qubit State by Using a Genuinely Entangled Six-Qubit State as a Quantum Channel

Ming-huang Sang

A scheme for quantum state sharing of an arbitrary single qubit state by using a genuinely entangled six-qubit state as a quantum channel is proposed.Firstly,the sender performs the Bell-state measurement and single qubit measurements on her qubits,respectively.Then any one of the two legitimate agents make a single qubit measurement on his qubit,and the other one(receiver) can reconstruct the original arbitrary single qubit state by performing appropriate unitary operation on his particle.The successful probability of this scheme is 100%.

Efficient Multiparty Quantum Secret Sharing with Greenberger–Horne–Zeilinger States

Deng Fu-Guo, Ping Zhou, Xihan Li +2 more

An efficient multiparty quantum secret sharing scheme is proposed with Greenberger–Horne–Zeilinger (GHZ) states following some ideas in quantum dense coding. The agents take the single-photon measurements on the photons received for eavesdropping check and exploit the four local unitary operations I , σ z , σ x and i σ y to code their message. This scheme has the advantage of high capacity as each GHZ state can carry two bits of information. The parties do not need to announce the measuring bases for almost all the photons, which will reduce the classical information exchanged largely. The intrinsic efficiency for qubits and the total efficiency both approach the maximal values.
