摘要：
We present two optimal quantum anti-cloning machines for real state in two dimensions, i.e., input state lying in the x-z equator. The first anti-cloning machine produces two outputs which are orthogonal to the input, and the second one produces two anti-parallel outputs for a single input state. The optimal fidelities are also derived.
