We explore how the quantum entanglement is modified in generalized uncertainty principle (GUP)-corrected mechanics by introducing coupled harmonic oscillator system. Constructing ground state $\rho_0$ and its reduced substate $\rho_A = \mbox{Tr}_B \rho_0$, we compute two measures of $\rho_0$, i.e. ${\cal E}_{EoF} (\rho_0) S_{von} (\rho_A)$ E}_{\gamma} S_{\gamma} (\rho_A)$, where $S_{von}$ $S_{\...
