Almost all quantum channels are equidistant

2018 · Journal of Mathematical Physics

In this work, we analyze properties of generic quantum channels in the case of large system size. We use random matrix theory and free probability to show that the distance between two independent random channels …

Cut-resistant links and multipartite entanglement resistant to particle loss

2019 · Physical Review A

In this work, we explore the space of quantum states composed of $N$ particles. To investigate entanglement resistant to particle loss, we introduce the notion of $m$-resistant states. A quantum state is $m$ resistant if …
