This work explores a falsiable prediction arising from the Stochastic Rupture (SR) framework: the possible existence of a fundamental upper mass scale for sustained quantum coherence in spatial superpositions. Within this model, collapse occurs when the local von Neumann entropy approaches a signicant fraction η of the Bekenstein information bound, with η a representative parameter of order 0.11. For eective branch masses above roughly m ∼ 10−10 kg, the predicted collapse times can approach or fall below typical quantum gate operation timescales, even in low-noise environments. This prediction is independent of standard environmental decoherence and diers from conventional objective collapse models (Continuous Spontaneous Localization or DiósiPenrose) in its quadratic dependence on the wavepacket width σx and in the existence of a distinct collapse regime at zero spatial separation. Independent simulations by Balaji & Punch (2025) 3 demonstrate that mass-dependent decoherence channels are detectable in principle using quantum circuit simulators, supporting the feasibility of targeted experimental tests. A dedicated matter-wave or optomechanical interferometry experiment varying the ratio σx/d could constrain or support the proposed threshold.
