"Universal distillation of quantum resources"
Abstract: Distillation of quantum resources is a central task in quantum information science, with important consequences for real-world noisy quantum information processing and for understanding the nature of quantum mechanics. Generally, distillation protocols perform well only under the strong assumption that the inputs are independent and identically distributed (i.i.d.). In this talk, I will introduce the concept of universal resource distillation, which asks whether it is possible to always produce an output that has higher quality than all inputs, no matter what those inputs are. I will explain why this is not possible for entanglement. Surprisingly however, it can be done in the context of communication, which leads to a new entanglement-assisted method that can take any collection of channels and produce one that outperforms them all.
