We introduce two families of criteria for detecting and quantifying the entanglement of a
bipartite quantum state of arbitrary local dimension. The first is based on measurements in …

We present an approach to estimate the operational distinguishability between an entangled
state and any separable state directly from measuring an entanglement witness. We show …

Efficiently detecting entanglement based on measurable quantities is a basic problem for
quantum information processing. Recently, the measurable quantities called partial …

Detecting entanglement in many-body quantum systems is crucial but challenging, typically
requiring multiple measurements. Here, we establish a class of states where measuring …

The concept of entanglement and separability of quantum states is relevant for several fields
in physics. Still, there is a lack of effective operational methods to characterise these …

Quantum mechanics features a variety of distinct properties such as coherence and
entanglement, which could be explored to showcase potential advantages over classical …

Quantum decoherence due to imperfect manipulation of quantum devices is a key issue in
the noisy intermediate-scale quantum (NISQ) era. Standard analyses in quantum …

Legitimate quantum operations must adhere to principles of quantum mechanics,
particularly the requirements of complete positivity and trace preservation. Yet, non …

Quantum state tomography is the standard technique for reconstructing a quantum state
from experimental data. In the regime of finite statistics, experimental data cannot give …

Although quantum entanglement is an important resource, its characterization is quite
challenging. The partial transposition is a common method to detect bipartite entanglement …
