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…

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…

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…
