Hello,

I have this value for element of my list:

And I have this code:

function [A,B] = CHSHmeasurement(d)
    A=zeros(d,d,2,d);
    B=A;
    projectors_of_sigma_x = [1/sqrt(2)*[1;1],1/sqrt(2)*[1;-1]];
    for k = 1:d
        for l =1:length(projectors_of_sigma_x)
            %A(k,k,1,k)=projectors_of_sigma_x(l);
            A(:,:,1,k)=projectors_of_sigma_x(l);
        end
    end
end    
    

However I have the same element for A although I have the different elements in the projectors_of_sigma_x

There is no error message but as you can see I have different value for projectors_of_sigma_x = [1/sqrt(2)*[1;1],1/sqrt(2)*[1;-1]]; (v1 and v2 you can see from the images clearly) but for the A(:,:1,1) and A(:,:,1,2) I have the same matrix and d is = 2

 for k = 1:d
        for l =1:d
            A(:,:,1,k) = repmat(projectors_of_sigma_x(:,k), 1, d);
        end
 end

I suggest you to read https://www.mathworks.com/company/newsletters/articles/matrix-indexing-in-matlab.html , first deal with 2D matrices before dealing with higher dimension matrices.

When do you need ? I don't have time to analyse that sorry :( . I see that you have asked the same question already!

Ahh no worries! I can wait (till the tuesday) Yeah I asked and each question includes different version of my combination because I have tried too many combiations
