Jing‐Ling Chen, Kang Xue, Mo‐Lin Ge · Chinese Physics Letters · 2009
We show that all pure entangled states of two d-dimensional quantum systems (i.e., two qudits) can be generated from an initial separable state via a universal Yang–Baxter matrix if one is assisted by local unitary transformations.
