  • Three-party quantum secret sharing based on phase Shift Operation
    Modern Physics Letters B, 2018
    Co-Authors: Huawang Qin, Raylin Tso, Yuewei Dai
    Abstract:

    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.

  • (t, n) Threshold quantum secret sharing using the phase Shift Operation
    Quantum Information Processing, 2015
    Co-Authors: Huawang Qin, Xiaohua Zhu, Yuewei Dai
    Abstract:

    A (t, n) threshold quantum secret sharing scheme is proposed, in which the secret is a quantum state, and the dealer encodes the secret through the phase Shift Operation. The participants perform the phase Shift Operations on the quantum state according to their private keys, and any t out of the n participants can use the Lagrange interpolation to recover the original quantum state. Compared to the existing schemes, the proposed scheme is simpler and more efficient.

  • Public-key quantum signature based on phase Shift Operation
    Modern Physics Letters B, 2020
    Co-Authors: Huawang Qin, Wallace K. S. Tang
    Abstract:

    A public-key quantum signature (QS) scheme is proposed, in which the phase Shift is the private key and the quantum state after the phase Shift Operation is the public key. The signatory uses the private key to encode the quantum state, and uses the Bell measurement to generate the signature. The receiver performs the unitary Operation according to the signature, and then compares the quantum state with the public key to verify the signature. Our scheme does not need a trusted arbitrator, and the signature can be verified by the receiver publicly. Compared to the existing arbitrated QS scheme, our scheme will be more practical.

  • SMC - Weighted Threshold Quantum Secret Sharing Based on the Chinese Remainder Theorem and the Phase Shift Operation
    2018 IEEE International Conference on Systems Man and Cybernetics (SMC), 2018
    Co-Authors: Wei-lun Yeoh, Xing-yu Chen, Guo-jyun Zeng, Yao-hsin Chou
    Abstract:

    Threshold quantum secret sharing schemes are incredibly complex systems, making even constructed schemes so complicated as to be very difficult to implement. In addition, most of these schemes share classical information rather than true quantum information. Weighted threshold quantum secret sharing schemes are especially complex, so much so that, to date, no one has been able to successfully construct one. In light of this, this study uses the Chinese Remainder Theorem and performs the phase Shift Operation on a quantum state to build a weighted threshold secret sharing scheme. The proposed scheme allocates each participant in the scheme their own weight. The dealer then selects a key and encodes it on a secret of quantum state with the phase Shift Operation. One this is achieved, the dealer divides the key into partial keys, and sends them to the participants. When the sum of the weights of participants is greater than or equal to a fixed threshold, the participants can reconstruct the secret and obtain the quantum information. The proposed scheme is an efficient and flexible weighted threshold quantum secret sharing and is simpler and easier to implement than earlier ones.
