System-environment dynamics of GHZ-like states in noninertial frames
Tinggui Zhang, Hong Yang, Shao-Ming Fei
Quantum coherence, quantum entanglement and quantum nonlocality are important resources in quantum information precessing. However, decoherence happens when a quantum system intera…
Criteria for SLOCC and LU Equivalence of Generic Multi-qudit States
Jingmei Chang, Naihuan Jing, Tinggui Zhang
In this paper, we study the stochastic local operation and classical communication (SLOCC) and local unitary (LU) equivalence for multi-qudit states by mode- matricization of th…
Quantum Bell nonlocality cannot be shared under a special kind of bilateral measurements for high-dimensional quantum states
Tinggui Zhang, Qiming Luo, Xiaofen Huang
Quantum Bell nonlocality is an important quantum phenomenon. Recently, the shareability of Bell nonlocality under unilateral measurements has been widely studied. In this study, we…
Two Quantum Proxy Blind Signature Schemes Based on Controlled Quantum Teleportation
Qiming Luo, Tinggui Zhang, Xiaofen Huang +1
We present a scheme for teleporting an unknown, two-particle entangled state with a message from a sender (Alice) to a receiver (Bob) via a six-particle entangled channel. We also…
Sharing Quantum Nonlocality in Star Network Scenarios
Tinggui Zhang, Naihuan Jing, Shao-Ming Fei
The Bell nonlocality is closely related to the foundations of quantum physics and has significant applications to security questions in quantum key distributions. In recent years,…
Separability criteria based on the Weyl operators
Xiaofen Huang, Tinggui Zhang, Ming-Jing Zhao +1
Entanglement as a vital resource for information processing can be described by special properties of the quantum state. Using the well-known Weyl basis we propose a new Bloch deco…
