We investigate the impact of Hilbert-space truncation upon the entanglement of an initially maximally entangled m× m bipartite quantum state, after propagation under an entanglement-preserving n× n (n⩾ m) unitary. Truncation—physically enforced, eg, by a detector's finite cross section—projects the state onto an s× s-dimensional subspace (3⩽ s⩽ n). For a random local unitary evolution, we obtain a simple analytical formula that expresses the truncation-induced entanglement loss as a function of n, m and s.
