Disentanglement Cost of Quantum States

Author(s): Mario Berta and Christian Majenz
We show that the minimal rate of noise needed to catalytically erase the entanglement in a bipartite quantum state is given by the regularized relative entropy of entanglement. This offers a solution to the central open question raised in [Groisman et al., Phys. Rev. A 72, 032317 (2005)] and complem...
