This work presents the first digital quantum simulation of the five-dimensional τ-delay field model, a theoretical framework unifying particle physics and gravity via a dynamical time-delay scalar field in a compact extra dimension.Using a two-qubit controlled-phase Hamiltonian implemented on IBM’s Qiskit AerSimulator, the study models the interaction between a τ-delay excitation and a delay memory register.The simulation identifies: a sharp resonance at τ* = 0.050 corresponding to a ≈ 6 TeV scalar-like excitation under compactification scale R⁻¹ = 0.6 TeV, and undamped coherent oscillations in survival probability at τ = 0.25, revealing a long-lived quasi-stable mode. These results provide computational validation for the theoretical predictions of high-energy quasi-resonant states arising from 5D delay dynamics.
