Quantum Fisher information-based detection of genuine tripartite entanglement
Long-Mei Yang, Bao-Zhi Sun, Bin Chen +2
Genuine multipartite entanglement plays important roles in quantum information processing. The detection of genuine multipartite entanglement has been long time a challenging probl…
Total variance and invariant information in complementary measurements
Bin Chen, Shao-Ming Fei
We investigate the total variance of a quantum state with respect to a complete set of mutually complementary measurements and its relation to the Brukner-Zeilinger invariant infor…
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…
Average coherence with respect to complementary measurements
Bin Chen, Shao-Ming Fei
We investigate the average coherence with respect to a complete set of complementary measurements. By using a Wigner-Yanase skew information-based coherence measure introduced in […
Estimation on geometric measure of quantum coherence
Hai-Jun Zhang, Bin Chen, Ming Li +2
We study the geometric measure of quantum coherence recently proposed in [Phys. Rev. Lett. 115, 020403 (2015)]. Both lower and upper bounds of this measure are provided. These boun…
