Characterizing the superposition of arbitrary random quantum states and a known quantum state
Bo Li, Xiao-Bin Liang, Shao-Ming Fei
The superposition of states is one of the most fundamental issues in the quantum world. Generally there do not exist physical operations to superpose two unknown random states with…
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…
Photonic implementation of quantum information masking
Zheng-Hao Liu, Xiao-Bin Liang, Kai Sun +8
Masking of quantum information spreads it over nonlocal correlations and hides it from the subsystems. It is known that no operation can simultaneously mask all pure states [Phys.…
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…
Impossibility of masking a set of quantum states of nonzero measure
Xiao-Bin Liang, Bo Li, Shao-Ming Fei +1
We study the quantum information masking based on isometric linear operators that distribute the information encoded in pure states to the correlations in bipartite states. It is s…
