Compatibility conditions from multipartite entanglement measures
Jian-Ming Cai, Zheng-Wei Zhou, Shun Zhang +1
We consider an arbitrary d_{1}\otimes d_{2}\otimes ... \otimes d_{N} composite quantum system and find necessary conditions for general m-party subsystem states to be the reduced s…
Local Operations in qubit arrays via global but periodic Manipulation
Zheng-Wei Zhou, Yong-Jian Han, Guang-Can Guo
We provide a scheme for quantum computation in lattice systems via global but periodic manipulation, in which only effective periodic magnetic fields and global nearest neighbor in…
Information-Theoretic Measure of Genuine Multi-Qubit Entanglement
Jian-Ming Cai, Zheng-Wei Zhou, Xing-Xiang Zhou +1
We consider pure quantum states of N qubits and study the genuine N-qubit entanglement that is shared among all the N qubits. We introduce an information-theoretic measure of genui…
Fully multi-qubit entangled states
Jian-Ming Cai, Zheng-Wei Zhou, Guang-Can Guo
We investigate the properties of different levels of entanglement in graph states which correspond to connected graphs. Combining the operational definition of graph states and the…
Fidelity, entanglement, and information complementarity relation
Jian-Ming Cai, Zheng-Wei Zhou, Guang-Can Guo
We investigate the dynamics of information in isolated multi-qubit systems. It is shown that information is in not only local form but also nonlocal form. We apply a measure of loc…
Local Distinguishability of Orthogonal Quantum States and Generators of SU(N)
Ming-Yong Ye, Wei Jiang, Ping-Xing Chen +3
We investigate the possibility of distinguishing a set of mutually orthogonal multipartite quantum states by local operations and classical communication (LOCC). We connect this pr…
