A Criterion to identify maximally entangled nine-qubit state
Xinwei Zha, Irfan Ahmed, Da Zhang +1
We present a generalized criterion for maximally entangled nine-qubit states, whose minimum averaged subsystem purity should be equal to 1/14. In this note, we prove that absolutel…
Construct SLOCC invariants via square matrix
Xin-Wei Zha
We define a square matrices, by which some stochastic local operations and classical communication (SLOCC) invariants can be obtained. The relation of SLOCC invariants and characte…
A monogamy equalities of complementarity relation and distribute entanglement for multi-qubit pure states
Xin-wei Zha, Yanpeng Zhang
We propose a method to detect genuine quantum correlation for multi-qubit pure states. We then derive a complementarity relations for pure quantum states of N qubits. We prove that…
The superposition invariance of unitary operators and maximally entangled state
Xin-Wei Zha, Yun-Guang Zhang, Jian-Xia Qi
In this paper, we study the superposition invariance of unitary operators and maximally entangled state respectively. Furthermore, we discuss the set of orthogonal maximally entang…
3-Uniform states and orthogonal arrays
Xin-wei Zha, Irfan Ahmed, Yanpeng Zhang
In a recent paper (Phys. Rev. A 90, 022316 (2014) ), Goyeneche et al. established a link between the combinatorial notion of orthogonal arrays and k-uniform states and present open…
Exploring maximally multipartite entanglement of even n qubits with N-tangle
Xin-Wei Zha, Jian-Xia Qi, Yun-Guang Zhang
A necessary condition of the maximally multipartite entangled states (MMES) is given via n-tangle. The condition shows that the n-tangle equal zero for the four-, and eight-qubit o…
