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…
Entanglement enhanced distinguishability of coherence-breaking channels
Long-Mei Yang, Tao Li, Shao-Ming Fei +1
Originated from the superposition principle in quantum mechanics, coherence has been extensively studied as a kind important resource in quantum information processing. We investig…
Coherence of Purification
Arun Kumar Pati, Long-Mei Yang, Chiranjib Mukhopadhyay +2
We introduce a quantity called the coherence of purification which can be a measure of total quantumness for a single system. We prove that coherence of purification is always more…
Entanglement-breaking of quantum dynamical channels
Long-Mei, Yang Tao Li, Shao-Ming Fei +1
Entanglement is a key issue in the quantum physics which gives rise to resources for achieving tasks that are not possible within the realm of classical physics. Quantum entangleme…
Tighter weighted polygamy inequalities of multipartite entanglement in arbitrary-dimensional quantum systems
Bin Chen, Long-Mei Yang, Shao-Ming Fei +1
We investigate polygamy relations of multipartite entanglement in arbitrary-dimensional quantum systems. By improving an inequality and using the th () power of ent…
