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 […
