Characterization Of Incoherent Operators And Strongly Incoherent Operators

In recent years,scientists have successfully combined quantum theory and information science,so"quantum information" has emerged as the emerging branch of the discipline,and has become a current research hot spot and made important progress.This paper uses the method of operator algebra and matrix theory the maximally incoherent operations,incoherent operations,genuinely incoherent operations,and fully incoherent operations.Firstly,we give the specific forms of the maximally incoherent operations,incoherent operations,genuinely incoherent operations and fully incoherent operations.Secondly,we get some the relevant conclusions of the maximally incoherent operations,incoherent operations,genuinely incoherent operations and fully incoherent operations.Finally,the relevant conclusions are explained by definite quantum operations.This article is divided into three chapters,the specific contents are as follows:The first chapter first introduces some of the symbols used in this article,then gives some basic concepts,assumptions and theorems of quantum coherence,and introduces their development process,research significance and current status.The second chapter first introduces the coherence of the maximally incoherent operations,incoherent operations,secondly gives the expression of the coherence,In addition,we start from the incoherent quantum operations,this paper studies the coherence of a special unguided quantum operation.The third chapter first introduces the coherence of genuinely incoherent operations,then we give the concrete form of Kraus operators of fully incoherent quantum operations in some fixed basis.
