内容简介：Strong quantum nonlocality is a stronger manifestation of nonlocality in multipartite systems through the notion of local irreducibility in all bipartitions. Known results for the sets of strongly nonlocal orthogonal states work for only product states. Based on the Rubik’s cube, we construct such sets consisting of dxdxd entangled states for all d>=3. Consequently, we answer an open problem by [PRL 122, 040403 (2019)], namely strongly nonlocal orthogonal entangled bases do exist. Further, we propose two entanglement-assisted protocols for local discrimination. Each protocol consumes less entanglement resources than the teleportation-based protocol on average. Our results exhibit the phenomenon of strong quantum nonlocality with entanglement. We also propose the latest result on strongly nonlocal orthogonal product sets in some multipartite systems.
