초록본문(Abstract) Lomonaco and Kauffman introduced knot mosaics in their work on quantum knots. This definition is intended to represent an actual physical quantum system. A {\em knot $n$-mosaic} is an $n\times n$ matrix of 11 kinds of specific mosaic tiles representing a knot or a link. In this paper, we consider the {\em alternating mosaic number} of an alternating knot $K$ which is defined as the smallest integer $n$ for which $K$ is representable as a reduced alternating knot $n$-mosaic. We define a signed mosaic graph and a diagonal grid graph and construct Hamiltonian cycles derived from the diagonal grid graphs. Using the cycles, we completely determine the alternating mosaic number of torus knots of type $(2,q)$ for $q\geq 2$, which grows in an order of $q^{1/2}$.
