The quantum phase transition in two-dimensional Ising spin glasses exhibits a super-algebraic closing of the energy gap at the critical point, but the gap closing remains algebraic if the symmetry of possible excitations is restricted, which is experimentally achievable.

We find that, in the quantum transition of Ising spin glass, the closing of the gap at the critical point can remain algebraic by restricting the symmetry of possible excitations, which is crucial for quantum annealing.
