Local-dephasing-induced entanglement sudden death in two-component finite-dimensional systems
Kevin Ann, Gregg S. Jaeger · Physical Review A · 2007
Entanglement sudden death (ESD), the complete loss of entanglement in finite time, is demonstrated to occur in a class of bipartite states of qudit pairs of any finite dimension $d>2$, when prepared in so-called ``isotropic states'' and subject to multilocal dephasing noise alone. This extends previous results for qubit pairs [T. Yu and J. H. Eberly, Phys. Rev. Lett. 97, 140403 (2006)] to all qudit pairs with $d>2$.
