Thermodynamic Viability and the Universality of Feynman Matter
Rowan Brad Quni-Gudzinas
Abstract
The dominant paradigm for universal quantum computation, predicated on active error correction, is fundamentally constrained by a thermodynamic wall, a phase transition where the entropy produced by control operations catastrophically overwhelms the system. This study quantifies this constraint, identifying a colossal “Protection Deficit” of approximately $10^{12}$ between the metabolic efficiency of biological systems and the energy cost of state-of-the-art engineered quantum processors. To resolve this thermodynamic crisis, we propose a shift from “forced” discrete control to “geodesic” evolution on a quantum information manifold. Through a stochastic master equation simulation, we compare a high-forcing “Shor” protocol against a low-forcing “Feynman” protocol. The simulation results are definitive: the Shor protocol breaches the thermodynamic wall in microseconds, dissipating 52.5 J, while the Feynman protocol, leveraging passive protection from high topological complexity ($Q=5$) and chirality ($\lambda=0.9$), maintains a fidelity of $>0.99$ for over a second with a minimal energy cost of 4.0 J. This work refutes the “Myth of Specialization” by invoking the AQC equivalence theorem, which proves that Hamiltonian-based systems (“Feynman Matter”) are computationally universal. We argue that Feynman Matter is not a niche simulator but the only thermodynamically viable substrate for a universal quantum computer, acting as a “Layer 0” error suppression layer that makes a subsequent, minimal active code tractable. This hybrid model resolves the Feynman-Shor bifurcation, with biological intelligence, validated by recent lithium isotope experiments, serving as the ultimate existence proof of a universal geodesic computer.
