Abstract

We present a semiquantum secret sharing protocol by using two-particle entangled states in which quantum Alice shares a secret key with two classical parties, Bob and Charlie. Classical Bob and Charlie are restricted to measuring, preparing a particle in the computational basis, or reflecting the particles. None of them can acquire the secret unless they collaborate. We also show the protocol is secure against eavesdropping.

Semiquantum secret sharing using entangled states

Qin Li, Wai Hong Chan, Dongyang Long

Secret sharing is a procedure for sharing a secret among a number of participants such that only the qualified subsets of participants have the ability to reconstruct the secret. Even in the presence of eavesdropping, secret sharing can be achieved when all the members are quantum. So what happens if not all the members are quantum? In this paper, we propose two semiquantum secret sharing protocols by using maximally entangled Greenberger-Horne-Zeilinger-type states in which quantum Alice shares a secret with two classical parties, Bob and Charlie, in a way that both parties are sufficient to obtain the secret, but one of them cannot. The presented protocols are also shown to be secure against eavesdropping.

Semiquantum Key Distribution Using Entangled States

Recently, Boyer et al. presented a novel semiquantum key distribution protocol [ Phys. Rev. Lett. 99 (2007) 140501 ] by using four quantum states, each of which is randomly prepared in the Z or X basis. Here we present a semi-quantum key distribution protocol by using maximally entangled states in which quantum Alice shares a secret key with classical Bob. Quantum Alice has the ability to prepare Bell states and perform Bell basis or computational basis measurement. Classical Bob is restricted to measuring, preparing a particle in the computational basis, reflecting or reordering the particles. The qubit efficiency of the protocol improves to 50% and the protocol can be modified to a measure-resend protocol or a protocol without quantum memory. We also show that the protocol is secure against eavesdropping.

We present a quantum information splitting(QIS) protocol by using four-particle entangled states in which quantum Alice shares a secret key with three classical parties,Bob,Charlie and David.None of them can acquire the secret unless they mutuallg collaborate and each receiver has the same authority for getting the sender′s secret.The receivers have the same probability to get the original secret and the probability is 1.

Multiparty semiquantum secret sharing based on rearranging orders of qubits

Gan Gao, Yue Wang, Dong Wang

Based on the assumption of a perfect qubit, Boyer et al. proposed a novel semiquantum key distribution protocol [Phys. Rev. Lett. 99 (2007) 140501], in which quantum Alice shares a secret key with classical Bob. In this paper, we use Bell states to propose a multiparty semiquantum secret sharing (MSQSS) protocol, in which only the boss is quantum and all agents are classical. Classical agents are restricted to performing measurements in a computational basis and rearranging orders of qubits. Unless all classical agents collaborate, no subset of them can obtain the secret of the quantum boss. Also, we show that this proposed protocol is secure against eavesdropping.

A novel semi-quantum secret sharing scheme using entangled states

Ai Han Yin, Tong Yan

Semi-quantum secret sharing (SQSS) can transmit secret messages. Most existing SQSS protocols can only use one or two specific entangled states to share unspecific or specific classical message. In this paper, we propose a novel SQSS protocol using N different unspecific two-particle entangled state [Formula: see text], [Formula: see text] to share unspecific message, in which quantum Alice can transmit classical messages with classical Bob and Charlie. In addition, we have proved that the protocol can strongly resist some forms of eavesdropping.

Quantum secret sharing with classical Bobs

Lvzhou Li, Daowen Qiu, Paulo Mateus

Boyer, Kenigsberg, and Mor [Phys.Rev.Lett.99, 140501(2007)] proposed a novel idea of semi-quantum key distribution where a key can be securely distributed between Alice who can perform any quantum operation and Bob who is classical. Extending the idea of “semiquantum” to other tasks of quantum information processing is of interest and worth considering. In this article, we consider the issue of semi-quantum secret sharing where a quantum participant Alice can share a secret key with two classical participants Bobs. After analyzing the existing protocol, we propose a new protocol of semi-quantum secret sharing. Our protocol is more realistic, since it utilizes product states instead of entangled states. We prove that any attempt of an adversary to obtain information necessarily induces some errors that the legitimate users could notice. 1
