Suppose \\alice and \\bob are located at different places and need to produce a target shared quantum state $\\rho$. In order to save quantum communication, they can choose to share a proper smaller quantum state $\\sigma$ first, and then turn $\\sigma$ to $\\rho$ by performing only local quantum operations and classical communications (LOCC). We hope $\\sigma$ is the optimal such that the quantum communication needed is as little as possible, which is called the generation cost of $\\rho$.
