Maximum Relative Entropy of Coherence for Quantum Channels
Zhi-Xiang Jin, Long-Mei Yang, Shao-Ming Fei +4
Based on the resource theory for quantifying the coherence of quantum channels, we introduce a new coherence quantifier for quantum channels via maximum relative entropy. We prove…
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…
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…
