DOI: 10.1038/s41598-021-82303-3
Abstract: In this paper we develop an approach for detecting entanglement, which is based on measuring quantum correlations and constructing a correlation matrix. The correlation matrix is then used for defining a family of parameters, named… read more here.

DOI: 10.1103/physrevlett.126.190502
Abstract: We study the detection of continuous-variable entanglement, for which most of the existing methods designed so far require a full specification of the devices, and we present protocols for entanglement detection in a scenario where… read more here.

DOI: 10.1103/physrevlett.128.110501
Abstract: The recognition of entanglement states is a notoriously difficult problem when no prior information is available. Here, we propose an efficient quantum adversarial bipartite entanglement detection scheme to address this issue. Our proposal reformulates the… read more here.

DOI: 10.1103/physrevlett.129.230503
Abstract: Entanglement detection is essential in quantum information science and quantum many-body physics. It has been proved that entanglement exists almost surely for a random quantum state, while the realizations of effective entanglement criteria usually consume… read more here.
