Multi-user quantum private comparison with scattered preparation and one-way convergent transmission of quantum states
Tian-Yu Ye, Zhao-Xu Ji
Quantum private comparison (QPC) aims to accomplish the equality comparison of the secrets from different users without disclosing their genuine contents by using the principles of…
Multi-party Quantum Private Comparison Based on the Entanglement Swapping of d-level Cat States and d-level Bell states
Zhao-Xu Ji, Tian-Yu Ye
In this paper, a novel multi-party quantum private comparison (MQPC) protocol with a semi-honest third party (TP) is proposed based on the entanglement swapping of d-level cat stat…
Demonstration of entanglement and coherence in GHZ-like state when exposed to classical environments with power-law noise
Atta Ur Rahman, ZhaoXu Ji, HuanGuo Zhang
Entanglement and coherence protection are investigated using the dynamical map of three non-interacting qubits that are initially prepared as maximally entangled GHZ-like states co…
Entanglement swapping under quantum information masking
Zhaoxu Ji, Peiru Fan, Atta Ur Rahman +1
Quantum information contained in single-particle states can be masked by mapping them to entangled states. In this paper, we consider entanglement swapping under the masking of qua…
Anonymous multi-party quantum computation with a third party
Zhaoxu Ji, Peiru Fan, Atta Ur Rahman +1
We reconsider and modify the second secure multi-party quantum addition protocol proposed in our original work. We show that the protocol is an anonymous multi-party quantum additi…
Probing tripartite entanglement and coherence dynamics in pure and mixed independent classical environments
Atta Ur Rahman, Muhammad Javed, Arif Ullah +6
Quantum information processing exploits non-local functionality that has led to significant breakthroughs in the successful deployment of quantum mechanical protocols. In this rega…
Probing multipartite entanglement, coherence and quantum information preservation under classical Ornstein-Uhlenbeck noise
Atta Ur Rahman, Muhammad Javed, Arif Ullah +1
We address entanglement, coherence, and information protection in a system of four non-interacting qubits coupled with different classical environments, namely: common, bipartite,…
Two-party quantum private comparison based on eight-qubit entangled state
Peiru Fan, Atta Ur Rahman, Zhaoxu Ji +3
The purpose of quantum private comparison (QPC) is to solve "Tierce problem" using quantum mechanics laws, where the "Tierce problem" is to judge whether the secret data of two par…
Security proof for quantum cryptography against entanglement-measurement attack
Zhaoxu Ji, Huanguo Zhang
Entanglement-measurement attack is one of the most famous attacks against quantum cryptography. In quantum cryptography protocols, eavesdropping checking is an effective means to r…
Entanglement swapping theory and beyond
Zhaoxu Ji, Huanguo Zhang
We focus on the general theory of entanglement swapping, including entanglement swapping of pure and mixed states. We also study the theory of entangled swapping chains, which can…
Cryptanalysis and improvement of several quantum private comparison protocols
Zhao-Xu Ji, Pei-Ru Fan, Huan-Guo Zhang +1
Recently, Wu et al. [Int. J. Theor. Phys. 58, 1854, (2019)] found a serious information leakage problem in Ye and Ji's quantum private comparison protocol [Int. J. Theor. Phys. 56,…
Entanglement swapping for Bell states and Greenberger-Horne-Zeilinger states in qubit systems
Zhaoxu Ji, Peiru Fan, Huanguo Zhang
We introduce a class of two-level multi-particle Greenberger-Horne-Zeilinger (GHZ) states, and study entanglement swapping between two systems for Bell states and the class of GHZ…
Greenberger-Horne-Zeilinger-based quantum private comparison protocol with bit-flipping
Zhaoxu Ji, Peiru Fan, Huanguo Zhang +1
By introducing a semi-honest third party (TP), we propose in this paper a novel QPC protocol using (n+1)- qubit (n \ge 2) Greenberger-Horne-Zeilinger (GHZ) states as information ca…
