Graph-theoretical Bounds on the Entangled Value of Non-local Games
نویسندگان
چکیده
We introduce a novel technique to give bounds to the entangled value of non-local games. The technique is based on a class of graphs used by Cabello, Severini and Winter in 2010. The upper bound uses the famous Lovász theta number and is efficiently computable; the lower one is based on the quantum independence number, which is a quantity used in the study of entanglementassisted channel capacities and graph homomorphism games. 1998 ACM Subject Classification G.2.3 Applications

On deciding the existence of perfect entangled strategies for nonlocal games
First, we consider the problem of deciding whether a nonlocal game admits a perfect finite dimensional entangled strategy that uses projective measurements on a maximally entangled shared state. Via a polynomial-time Karp reduction, we show that independent set games are the hardest instances of this problem. Secondly, we show that if every independent set game whose entangled value is equal to...

متن کاملBounds on the restrained Roman domination number of a graph
A {em Roman dominating function} on a graph $G$ is a function$f:V(G)rightarrow {0,1,2}$ satisfying the condition that everyvertex $u$ for which $f(u) = 0$ is adjacent to at least one vertex$v$ for which $f(v) =2$. {color{blue}A {em restrained Roman dominating}function} $f$ is a {color{blue} Roman dominating function if the vertices with label 0 inducea subgraph with no isolated vertex.} The wei...
متن کاملAn Anthropological Study of Folk Plays and Games with Focus on Fooman Town in Gilan Province
Play and Game are considered as the oldest cultural behaviors as the universal elements of human culture in all communities and groups. Gilan province in Iran, especially their villages, has a unique folklore especially its local games and plays. Nevertheless, it is necessary to document and analyze the immense information about the folklore in these villages before it vanishes in the sea of so...
متن کاملBounds on the outer-independent double Italian domination number
An outer-independent double Italian dominating function (OIDIDF)on a graph $G$ with vertex set $V(G)$ is a function$f:V(G)longrightarrow {0,1,2,3}$ such that if $f(v)in{0,1}$ for a vertex $vin V(G)$ then $sum_{uin N[v]}f(u)geq3$,and the set $ {uin V(G)|f(u)=0}$ is independent. The weight ofan OIDIDF $f$ is the value $w(f)=sum_{vin V(G)}f(v)$. Theminimum weight of an OIDIDF on a graph $G$ is cal...
