Diverging Entanglement Length in Gapped Quantum Spin Systems
F. Verstraete, M. A. Martin-Delgado, J. I. Cirac
We prove the existence of gapped quantum Hamiltonians whose ground states exhibit an infinite entanglement length, as opposed to their finite correlation length. Using the concept…

Single-Step Distillation Protocol with Generalized Beam Splitters
M. A. Martin-Delgado, M. Navascues
We develop a distillation protocol for multilevel qubits (qudits) using generalized beam splitters like in the proposal of Pan et al. for ordinary qubits. We find an acceleration w…

Distillation Protocols for Mixed States of Multilevel Qubits and the Quantum Renormalization Group
M. A. Martin-Delgado, M. Navascues
We study several properties of distillation protocols to purify multilevel qubit states (qudits) when applied to a certain family of initial mixed bipartite states. We find that it…
