Hello,
I have this matrix:
I saved this matrix in a list like : projectors_of_sigma_x_minus_sigma_z = [[(sqrt(2)-1);1],[(-sqrt(2)-1);1]];
and this is my code :
function B = CHSHmeasurement
B=zeros(2,2,2,2);
projectors_of_sigma_x_minus_sigma_z = [[(sqrt(2)-1);1],[(-sqrt(2)-1);1]];
B(:,:,2,1) = projectors_of_sigma_x_minus_sigma_z(1);
B(:,:,2,2) = projectors_of_sigma_x_minus_sigma_z(2);
end
But I have this result:
However I have not 1 as the second element of projectors_of_sigma_x_minus_sigma_z. I have [(-sqrt(2)-1);1] for the second element of projectors_of_sigma_x_minus_sigma_z(2); Where am I wrong ?

>> B=zeros(2,2,2,2);
projectors_of_sigma_x_minus_sigma_z = [[(sqrt(2)-1);1],[(-sqrt(2)-1);1]]
B(:,:,2,1) = projectors_of_sigma_x_minus_sigma_z(1)
B(:,:,2,2) = projectors_of_sigma_x_minus_sigma_z(2)
projectors_of_sigma_x_minus_sigma_z =
0.4142 -2.4142
1.0000 1.0000
B(:,:,1,1) =

B(:,:,2,1) =

And Sorry I missed your previous answer
projectors_of_sigma_x_minus_sigma_z(:, 1)
This is for what ?
