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…
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…
Amending coherence-breaking channels via unitary operations
Long-Mei Yang, Bin Chen, Tao Li +2
The coherence-breaking channels play a significant role in quantum information theory. We study the coherence-breaking channels and give a method to amend the coherence-breaking ch…
Dynamics of coherence-induced state ordering under Markovian channels
Long-Mei Yang, Bin Chen, Shao-Ming Fei +1
We study the dynamics of coherence-induced state ordering under incoherent channels, particularly four specific Markovian channels: amplitude damping channel, phase damping cha…
Ordering states with various coherence measures
Long-Mei Yang, Bin Chen, Shao-Ming Fei +1
Quantum coherence is one of the most significant theories in quantum physics. Ordering states with various coherence measures is an intriguing task in quantification theory of cohe…
