Universal Entanglement Distillation
Salvatore Tirone, Francesco Anna Mele, Vittorio Giovannetti +1
We present a universal entanglement distillation protocol that asymptotically achieves the distillable entanglement of any unknown bipartite state in a fixed finite dimension. That…
Exponential separation in sensing continuous signals via squeezing
