| Abstract: | In this paper, we discuss the ability of realizing Kraus operators and POVM measurements in a duality quantum computer. We prove that not all the Kraus operators can be realized in a duality quantum computer. We introduce a new type of duality quantum circuit, multi-duality circuit, by repeating the previous version of duality quantum circuit as a unit, and we can realize universal Kraus operators and POVM measurements with this new circuit. We also give a measure of the complexity of the Kraus operations in terms of the minimum number the units required to realize the Kraus operations in multi-duality circuit. |
