QGIDC: The World’s First Quantum Circuit Simulating Gravity-Induced Decoherence on Real Quantum Hardware

This study presents a groundbreaking experimental demonstration of gravity induced decoherence in quantum systems, achieved through the development and execution of the Quantum Gravity-Induced Decoherence Circuit (QGIDC) on IBM quantum hardware. This research provides the first measurable evidence of how gravitational effects can influence quantum entanglement, building upon and ex tending theoretical frameworks proposed by prominent physicists such as Roger Penrose and Gerard ’t Hooft. The experiments were conducted using both Qiskit simulators and real IBM quantum computers, including the advanced IBM Bris bane backend, with multiple repetitions to ensure scientific reproducibility. A com prehensive set of metrics—fidelity, purity, entropy, trace distance, measurement counts, and Bloch vector dynamics—were meticulously analyzed to differentiate gravity-induced noise from standard environmental decoherence. Additionally, a mathematical model is introduced to quantify the decoherence rate, while Bloch sphere visualizations offer a visual representation of qubit state evolution under gravitational influence. This work, completed as of 06:12 PM on Monday, May 19, 2025, marks the first empirical validation of gravity-induced decoherence, estab lishing a significant milestone in the quest to reconcile quantum mechanics with general relativity.
