QUBO: Exploring the QUantum Boundaries of many-body systems – an Odyssey into the gravity related collapse models

The default assumption of most research in quantum many-body systems is that the linear and deterministic Schroedinger evolution of the wave function is universally valid, which means that if we can isolate a quantum system, even for a googol of “bodies”, it will continue to manifest remarkable quantum features such as superposition of states and entanglement. This assumption, however, could be wrong! Objective Collapse Models (CM), proposed to solve the renowned measurement problem in quantum physics, modify quantum mechanics by adding to the standard Schroedinger equation non-linear stochastic terms, which dynamically collapse the wave function. These modifications entail that the bigger the many-body system, the faster its quantumness fades away. Among all CM the Diosi-Penrose (DP) one stands out as the visionary theory which identifies gravity as the mediator for the collapse. Within the QUBO project, we shall develop the DP collapse theory, expanding it to include realistic complex dispersive dynamics for the many-body systems. We will work out the experimental features of the spontaneous radiation predicted by the DP models, and perform dedicated measurements in the cosmic silence of the Gran Sasso underground laboratory with an innovative system based on a Broad Energy High Purity Germanium detector, using refined Monte Carlo simulations and statistical data analyses methods.
We propose an Odyssey into the quantum realm to stress and test its boundaries at unprecedented sensitivity/precision levels, and exploit our findings in other sectors, such as the Orch OR consciousness model, thereby situating QUBO within a broader interdisciplinary inquiry into human thought towards the advancement of science and humanity.
The project will lead to at least five high-quality research papers in major peer-reviewed physics journals and at least two dissemination articles. The findings will be presented at research conferences, workshops, and seminars.
