Abstract

The unextendible entangled basis with any arbitrarily given Schmidt number kk (UEBk) in Cd1Cd2\mathbb{C}^{d_1}\otimes\mathbb{C}^{d_2} is proposed in [Phys. Rev. A 90 (2014) 054303], 1<kmin{d1,d2}1<k\leq \min\{d_1,d_2\}, which is a set of orthonormal entangled states with Schmidt number kk in a d1d2d_1\otimes d_2 system consisting of fewer than d1d2d_1d_2 vectors which have no additional entangled vectors with Schmidt number kk in the complementary space. In this paper, we extend it to multipartite case and a general way of constructing (m+1)(m+1)-partite UEBk from mm-partite UEBk is proposed (m2m\geq 2). Consequently, we show that there are infinitely many UEBks in Cd1Cd2CdN\mathbb{C}^{d_1}\otimes\mathbb{C}^{d_2}\otimes\cdots\otimes\mathbb{C}^{d_N} with any dimensions and any N3N\geq3.
