Quantum Fisher information and coherence in one-dimensional spin models with Dzyaloshinsky-Moriya interactions
Biao-Liang Ye, Bo Li, Zhi-Xi Wang +2
We investigate quantum phase transitions in spin models using Dzyaloshinsky-Moriya (DM) interactions. We identify the quantum critical points via quantum Fisher information an…
Complete Optimal Convex Approximations of Qubit States under Distance
Xiao-Bin Liang, Bo Li, Biao-Liang Ye +2
We consider the optimal approximation of arbitrary qubit states with respect to an available states consisting the eigenstates of two of three Pauli matrices, the -distance of…
Quantum correlations in critical system and LMG model
Biao-Liang Ye, Bo Li, Xianqing Li-Jost +1
We investigate the quantum phase transitions for the spin-1/2 chains via the quantum correlations between the nearest and next to nearest neighbor spins characterized by nega…
A note on the Bloch representation of absolutely maximally entangled states
Bo Li, Shuhan Jiang, Shao-Ming Fei +1
The absolutely maximally entangled (AME) states play key roles in quantum information processing. We provide an explicit expression of the generalized Bloch representation of AME s…
