DOI: 10.1007/s11128-019-2349-8

Abstract: Entanglement is a key issue in the quantum physics which gives rise to resources for achieving tasks that are not possible within the realm of classical physics. Quantum entanglement varies with the evolution of the… read more here.

DOI: 10.1063/1.5024385

Abstract: We analyze certain class of linear maps on matrix algebras that become entanglement breaking after composing a finite or infinite number of times with themselves. This means that the Choi matrix of the iterated linear… read more here.

DOI: 10.1088/1751-8121/ade102

Abstract: Entanglement breaking (EB) channels, as completely positive and trace-preserving linear operators, sever the entanglement between the input system and other systems. In the realm of infinite-dimensional systems, a related concept known as strongly EB (SEB)… read more here.

DOI: 10.1103/physrevlett.134.080803

Abstract: A fundamental limitation of quantum communication is that a single qubit can carry at most one bit of classical information. For an important class of quantum communication channels, known as entanglement breaking, this limitation holds… read more here.
