We compute the low-energy quantum states and low-frequency dynamical susceptibility of a quantum generalization of the two-dimensional Edwards-Anderson spin glass, obtaining exact numerical results for system sizes much larger than previously accessible. The ground state is a complex superposition of a substantial fraction of all the classical ground states… CONTINUE READING
