    "abstract": "A quantum Latin square of order $n$ (denoted as QLS$(n)$) is an $n\\times n$ array whose entries are unit column vectors from the $n$-dimensional Hilbert space $\\mathcal{H}_n$, such that each row and column forms an orthonormal basis. Two unit vectors $|u\\rangle, |v\\rangle\\in \\mathcal{H}_n$ are regarded as identical if there exists a real number $\\theta$ such that $|u\\rangle=e^{i\\theta}|v\\rangle$; otherwise, they are considered distinct. The cardinality $c$ of a QLS$(n)$ is the number of distinct vectors in the array. In this note,we use sub-QLS$(6)$ to prove that for any integer $m\\geq 2$ and any $c\\in [6m,36m^2]\\setminus \\{6m+1\\}$, there is a QLS$(6m)$ with cardinality $c$.",
