Common Coherence Witnesses and Common Coherent States
Bang-Hai Wang, Zi-Heng Ding, Zhihao Ma +1
We show the properties and characterization of coherence witnesses. We show methods for constructing coherence witnesses for an arbitrary coherent state. We investigate the problem…
Tomographic Witnessing and Holographic Quantifying of Coherence
Bang-Hai Wang, Si-Qi Zhou, Zhihao Ma +1
The detection and quantification of quantum coherence play significant roles in quantum information processing. We present an efficient way of tomographic witnessing for both theor…
Entangled states in the role of witnesses
Bang-Hai Wang
Quantum entanglement lies at the heart of quantum mechanics and quantum information processing. In this work, we show a new framework where entangled states play the role of witnes…
A sufficient condition of violating the SPA conjecture
Bang-Hai Wang, Dong-Yang Long
Based on the general form of entanglement witnesses constructed from separable states, we first show a sufficient condition of violating the structural physical approximation (SPA)…
