We present an overview of the quantitative theory of single-copy entanglement in finite-
dimensional quantum systems. In particular we emphasize the point of view that different …

This paper investigates how to reduce the number of measurement configurations needed
for sufficiently precise entanglement quantification. Instead of analytical formulae, we …

Many-body quantum systems can be characterized using the notions of k-separability and
entanglement depth. A quantum state is k-separable if it can be expressed as a mixture of k …

A Werner state, which is the singlet Bell state affected by white noise, is a prototype example
of states, which can reveal a hierarchy of quantum entanglement, steering, and Bell …

Using the approach offered by quantum speed limit, we show that geometric measure of
multipartite entanglement for pure states [T.-C. Wei and PM Goldbart, Phys. Rev. A 68 …

Entanglement, one of the central mysteries of quantum mechanics, plays an essential role in
numerous tasks of quantum information science. A natural question of both theoretical and …

The detection of entangled states is essential in both fundamental and applied quantum
physics. However, this task proves to be challenging, especially for general quantum states …

We propose and experimentally implement an efficient procedure based on entanglement
swapping to determine the Bell nonlocality measure of Horodecki et al.[Phys. Lett. A 200 …

Detecting and quantifying quantum entanglement of a given unknown state poses problems
that are fundamentally important for quantum information processing. Surprisingly, no direct …

We describe a direct method to determine the negativity of an arbitrary two-qubit state in
experiments. The method is derived by analyzing the relation between the purity, negativity …
