Mutually unbiased measurement based entanglement witnesses
Tao Li, Le-Min Lai, Shao-Ming Fei +1
We study entanglement witness and present a construction of entanglement witnesses in terms of the mutually unbiased measurements (MUMs). These witnesses include the entanglement w…
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…
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…
On -convergence of the Biggins martingale with complex parameter
Alexander Iksanov, Xingang Liang, Quansheng Liu
We prove necessary and sufficient conditions for the -convergence, , of the Biggins martingale with complex parameter in the supercritical branching random walk. The resu…
Learning Transferable Self-attentive Representations for Action Recognition in Untrimmed Videos with Weak Supervision
Xiao-Yu Zhang, Haichao Shi, Changsheng Li +3
Action recognition in videos has attracted a lot of attention in the past decade. In order to learn robust models, previous methods usually assume videos are trimmed as short seque…
Cohomological invariants of representations of 3-manifold groups
Haimiao Chen
Suppose is a discrete group, and , with an abelian group. Given a representation , with a closed 3-manifold, put $F(M,ρ)=\langle(Bρ)^\ast[…
