The quantum dynamics process, such as thermalization and information scrambling, is not immune to non-unitary operations. In this work, the authors investigate the local projective measurements in the quantum dynamics of a non-integrable lattice model. The phase diagram features a stable volume-law, entangling, phase with finite small measurement rate and an area-law, disentangling, phase with large measurement rate. Scaling behaviors at the critical point suggest the scale invariance and a single universality class of criticality.
