Steered quantum coherence and quantum Fisher information in spin-chain system
Biao-Liang Ye, Yao-Kun Wang, Shao-Ming Fei
In this paper, we investigate steered quantum coherence, i.e., the norm of steered coherence and the relative entropy of steered coherence, and the quantum Fisher information…
Quantum Discord for multiqubit Systems
Bo Li, Chen-Lu Zhu, Xiao-Bin Liang +2
We evaluate analytically the quantum discord for a large family of multiqubit states. It is interesting to note that the quantum discord of three-qubits and five-qubits is the same…
Local quantum Fisher information and one-way quantum deficit in spin- Heisenberg chain with three-spin interaction
Biao-Liang Ye, Bo Li, Xiao-Bin Liang +1
We explore quantum phase transitions in the spin-1/2 chain with three-spin interaction in terms of local quantum Fisher information and one-way quantum deficit, together with…
Optimal approximations of available states and a triple uncertainty relation
Xiao-Bin Liang, Bo Li, Liang Huang +3
We investigate the optimal convex approximation of the quantum state with respect to a set of available states. By isometric transformation, we have presented the general mathemati…
Circuit QED: single-step realization of a multiqubit controlled phase gate with one microwave photonic qubit simultaneously controlling microwave photonic qubits
Biaoliang Ye, Zhen-Fei Zheng, Yu Zhang +1
We present a novel method to realize a multi-target-qubit controlled phase gate with one microwave photonic qubit simultaneously controlling target microwave photonic qubits.…
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…
