| Abstract: | We studied the kraus operator decomposition correspondingto incoherent quantum operations and strictly incoherent quantum operations by means of operator algebra and matrix theory. Firstly, we gavethe equivalence conditions of bounded linear operators as incoherent operators and the concrete forms of incoherent operators,and gave the method of characterizing incoherent quantum operations with incoherent operators. Secondly, we gave theconcrete forms of strongly incoherent operators and the method of characterizing strictly incoherent quantum operations with strongly incoherent operators, and gave the relationship between strictly incoherent quantum operations and incoherent quantum operations. |
