All the coordinates have equal values for \(x\) and \(y\). This is shown by the points on the line such as (10, 10) and (-4, -4). Graph A is \(y = -x\). All the coordinates have \(x\) and \(y ...

In recent years, special types of multipartite entangled states, the graph states 1,2,3, have become the centre of attention. They can be associated with graphs where each vertex represents a ...
