  "abstract": "Suppose that we have two entangled states $\\ket {\\phi_1}$, $\\ket{\\psi_1}$ that cannot be converted to any of other two states $\\ket{\\phi_2}$, $\\ket{\\psi_2}$ by local operations and classical communication. We analyze the possibility of locally transforming a superposition of $\\ket{\\phi_1}$ and $\\ket{\\psi_1}$ into a superposition of $\\ket{\\phi_2}$ and $\\ket{\\psi_2}$. By using the Nielsen's theorem we find the necessary and sufficient conditions for this conversion to be performed.",
