Abstract

In this work, we explore the space of quantum states composed of NN particles. To investigate the entanglement resistant to particles loss, we introduce the notion of mm-resistant states. A quantum state is mm-resistant if it remains entangled after losing an arbitrary subset of m particles, but becomes separable after losing a number of particles larger than mm. We establish an analogy to the problem of designing a topological link consisting of NN rings such that, after cutting any (m+1)(m + 1) of them, the remaining rings become disconnected. We present a constructive solution to this problem, which allows us to exhibit several distinguished NN-particles states with the desired property of entanglement resistance to a particle loss.
