Abstract
An entangled state is called resistant if it remains entangled after losing an arbitrary subset of particles but becomes fully separable after losing any number of particles larger than . Quinta et al. [Phys. Rev. A 100, 062329 (2019)] conjectured that for any -particle systems, there always exists an -resistant pure state of some local dimension . In this paper, we give two general constructions of -resistant pure states. One is from the mixtures of Dicke states, which provides strong -resistant pure -qubit states with or 5. The other is from classical error-correcting codes, which provides new -resistant pure qudit states for certain .
