Abstract

Huawang Qin*a & Raylin Tsoba School of Automatization, Nanjing University of Science and Technology, Nanjing, Chinab Department of Computer Science, National Chengchi University, Taipei, TaiwanCONTACT Huawang Qin qin_h_w@163.com School of Automatization, Nanjing University of Science and Technology, Nanjing 210094, ChinaABSTRACTAn efficient quantum secret sharing scheme is proposed. In the proposed scheme, the polarization state and the orbital angular momentum state of the particle can be utilized simultaneously. One state is used to bring the secret information, and the other state is used to check the eavesdropping. So all the particles can be used to transmit the secret, and the utilization efficiency of particles can achieve 100%. Compared to the existing schemes based on BB84 protocol or decoy particles, our scheme can increase the utilization efficiency of particles effectively.

High-capacity quantum secret sharing based on orbital angular momentum

Huawang Qin, Raylin Tso

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 by using Fourier transform on orbital angular momentum

Huawang Qin, Raylin Tso, Yuewei Dai

A quantum secret sharing scheme based on orbital angular momentum (OAM) is proposed. The dealer generates single particles in OAM basis or angular position (ANG) basis randomly. The participants encode their private keys into the particles through performing quantum Fourier transforms. Then the dealer can use the single‐particle measurements to get the shared secret. In the authors’ scheme, the secret is protected by the distinguishability of OAM basis and ANG basis. Compared to the traditional two‐dimensional schemes, the authors’ scheme can use the higher dimension of OAM to increase the detecting rate of eavesdropping, and enhance the security in practice. Besides, only the single particles are needed in their scheme. Compared to the schemes based on entangled particles, the authors’ scheme will be more practical with the present technology.

Three-party quantum secret sharing based on phase shift operation

Huawang Qin, Raylin Tso, Yuewei Dai

An efficient three-party quantum secret sharing scheme is proposed. The dealer uses the phase shift operation to encode the secret information into some EPR pairs. The members use the phase shift operation to decode the EPR pairs, and measure the EPR pairs to reconstruct the secret. Our scheme does not need the BB84 protocol or the decoy particles to protect the transmitted particles, and can use the phase shift operation to prevent the attacker from stealing secret information from the transmitted particles. So all the particles can be used to bring the secret information, and the utilization efficiency of the particles of 100% can be achieved. With the prevent technology, our scheme is more practical than the existing schemes.

A Quantum Secret Sharing Scheme Using Orbital Angular Momentum onto Multiple Spin States Based on Fibonacci Compression Encoding*

Hong Lai, Ming-Xing 明星 Luo 罗, Yong-Jian 永健 Xu 徐 +4 more

Abstract Since the use of a quantum channel is very expensive for transmitting large messages, it is vital to develop an effective quantum compression encoding scheme that is easy to implement. Given that, with the single-photon spin-orbit entanglement, we propose a quantum secret sharing scheme using orbital angular momentum onto multiple spin states based on Fibonacci compression encoding. In our proposed scheme, we can represent the frequency of any secret message which is typically collection of bits encodings of text or integers as a bitstring using the base Fibonacci sequence, which is encoded multiple spin states for secret shares transmitted to participants. We demonstrate that Fibonacci compression encoding carries excellent properties that enable us to achieve more robust quantum secret sharing schemes with fewer number of photons.

An efficient (t,n) threshold quantum secret sharing without entanglement

Huawang Qin, Yuewei Dai

An efficient [Formula: see text] threshold quantum secret sharing (QSS) scheme is proposed. In our scheme, the Hash function is used to check the eavesdropping, and no particles need to be published. So the utilization efficiency of the particles is real 100%. No entanglement is used in our scheme. The dealer uses the single particles to encode the secret information, and the participants get the secret through measuring the single particles. Compared to the existing schemes, our scheme is simpler and more efficient.
