We use nuclear magnetic resonance to experimentally generate a bound-entangled (more precisely: pseudo-bound-entangled) state, i.e., a quantum state which is nondistillable but nevertheless entangled. Our quantum system consists of three qubits. We characterize the produced state via state tomography to show that the created state has a positive partial transposition with respect to any bipartite splitting, and we use a witness operator to prove its pseudoentanglement.
