We show that the ground state of the periodic long range Josephson arrayfrustrated by magnetic field is a glass for a sufficiently large Josephsonenergies despite the absence of a quenched disorder. Like superconductors, thisglass state has non-zero phase stiffness and Meissner response; for smallerJosephson energies the glass "melts" and the ground state loses the phasestiffness and becomes insulating. We find the critical scaling behavior nearthis quantum phase transition: the excitation gap vanishes as (J-J_c)^2, thefrequency-dependent magnetic susceptibility behaves as \chi(\omega) ~\sqrt{\omega}\ln{\omega}.Comment: 9 pages, Latex, 3 figures in separated eps-file
