Quantum Contact H10: Cross-Path Optical Response Between Trajectories Sharing One Laser Source — Experimental Hypothesis and Testing Protocol (Bilingual EN–ES, v1.1)

Quantum Contact H10 is a bilingual (English–Spanish) preliminary scientific paper presenting a falsifiable experimental hypothesis and a prospective testing protocol. The project investigates whether a controlled physical intervention on one optical-fiber trajectory (S2) produces an additional, reproducible response in another trajectory (S1), both illuminated by a common laser source. The proposed five-module apparatus combines an ESP32-S3 microcontroller, BPW34 photodiodes, PMMA optical fibers, magnetic and electric interventions, and an auxiliary double-slit experiment. The paper describes the experimental architecture, hardware and software implementation, Python/Flask-based acquisition, calibration procedures, randomized real-versus-sham trials, statistical analysis, and criteria for supporting, constraining, or rejecting the hypothesis. The protocol explicitly addresses common-source fluctuations, electromagnetic interference, thermal effects, vibration, and other conventional explanations. **This is a hypothesis and experimental protocol, not a report of confirmed H10 results.** No novel quantum interaction or photon entanglement is claimed.
