ket = sum(tmpI(:,2:D),2);
The sum over the second dimension of a 2d array is going to be a column vector.
temp0 = symsum(exp(-abs(alpha(k))^2 * alpha(k)^n / sqrt(factorial(n)) ), n, 0, 14)*ket;
symsum of a scalar expression is going to give a scalar result. You then multiply by the column vector, and that will give you a column vector result.
It therefore appears that your temp0 is already a column vector.

double() or vpa()
The exp() terms I tested were exp(-1e-9) to exp(-1e-15). Precision is low in that range but the values should be distinguishable from 1.

Here is the corrected code:

tmpI = eye(D);
ket = sum(tmpI(:,2:D),2);
syms n
ct = 6;
creation = circshift(diag(sqrt(0:1:(D-1))),-1);
annihilation = creation';
Vnorm = zeros(1,ct);
alpha = 0.03*(1:ct);
%loop for calculation
for k = 1:ct
temp0 = double(symsum(exp(-abs(alpha(k))^2 * alpha(k)^n / sqrt(factorial(n)) ), n, 0, 14)*ket);
ketalpha(k,:) = temp0; % Data from each iteration is stored
temp1 = annihilation*temp0 - alpha(k)*temp0;
V(k,:) = temp1; % Data from each iteration is stored
Vnorm(k) = temp1'*temp1;
end
