Locality in Nonsequential Quantum Operations

Miroljub Dugic

abstract: We give an example of fulfillment of the condition of locality--no information transfer between certain subsystems--in a tripartite quantum system whose dynamics can not be decomposed (non-sequential dynamics of the system). The three subsystems ($A$, $B$ and $C$) are designed such that $C$ interacts simultaneously with both $A$ and $B$, while there is not any interaction between $A$ and $B$. On this basis, we emphasize validity of the condition of locality in a realistic physical situation.
