Incompatibility probability of random quantum measurements
Lin Zhang, Hua Xiang, Xianqing Li-Jost +1
Incompatibility of quantum measurements is of fundamental importance in quantum mechanics. It is closely related to many nonclassical phenomena such as Bell nonlocality, quantum un…
Information transfer in generalized probabilistic theories based on weak repeatability
Zhaoqi Wu, Shao-Ming Fei, Xianqing Li-Jost +1
Information transfer in generalized probabilistic theories (GPT) is an important problem. We have dealt with the problem based on repeatability postulate, which generalizes Zurek's…
Mutually unbiased measurement based entanglement witnesses
Tao Li, Le-Min Lai, Shao-Ming Fei +1
We study entanglement witness and present a construction of entanglement witnesses in terms of the mutually unbiased measurements (MUMs). These witnesses include the entanglement w…
Tighter constraints of multiqubit entanglement for negativity
Long-Mei Yang, Bin Chen, Shao-Ming Fei +1
We provide a characterization of multiqubit entanglement monogamy and polygamy constraints in terms of negativity. Using the square of convex-roof extended negativity (SCREN) and t…
Trade-off relation among genuine three-qubit nonlocalities in four-qubit systems
Li-Jun Zhao, Lin Chen, Yu-Min Guo +3
We study the trade-off relations satisfied by the genuine tripartite nonlocality in multipartite quantum systems. From the reduced three-qubit density matrices of the four-qubit ge…
Complete characterization of qubit masking
Xiao-Bin Liang, Bo Li, Shao-Ming Fei
We study the problem of information masking through nonzero linear operators that distribute information encoded in single qubits to the correlations between two qubits. It is show…
