Showing the Mirrorverse

We propose and experimentally validate a “Mirrorverse” extension to standard quantum circuits by pairing each conventional (Universe) qubit rotation Ry(+θ)\mathrm{R}_\mathrm{y}(+\theta)Ry(+θ) with its sign-inverted counterpart Ry(−θ)\mathrm{R}_\mathrm{y}(-\theta)Ry(−θ). Employing prime-based angles θ=1/p2\theta = 1/p^2θ=1/p2 with incremental circuit layers, we observe robust interference signatures that diverge markedly from the all-positive-phase control cases. Multi-basis measurements (Z, X, Y) reveal pronounced off-diagonal coherence unique to negative-phase rotations, corroborated by full state tomography indicating significant negativity—hence genuine entanglement—between the Universe and Mirrorverse registers. Furthermore, simulated noise models (depolarizing, amplitude damping, readout errors) demonstrate partial preservation of these phase-inverted interference features, suggesting feasible implementation on near-term devices. These findings reinforce the Duoverse principle of sign-opposed expansions, highlighting how prime-driven fractal recursion can amplify subtle negative-phase effects within conventional quantum computing frameworks.
