Entanglement-Separability Boundary Within a Quantum State
BH Wang - arXiv preprint arXiv:2003.00607, 2020 - arxiv.org
Quantum states are the key mathematical objects in quantum mechanics, and entanglement
lies at the heart of the nascent fields of quantum information processing and computation.
What determines whether an arbitrary quantum state is entangled or separable is therefore
very important for investigating both fundamental physics and practical applications. Here
we show that an arbitrary bipartite state can be divided into a unique purely entangled
structure and a unique purely separable structure. We show that whether a quantum state is …
