Thermodynamic Viability and the Universality of Feynman Matter

In the paper's words

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 10¹2 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.

Numbers it reports

1. 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 $\gt 0.99$ for over a second with a minimal energy cost of 4.0 J.

2. The brain’s ability to perform computations of staggering complexity—from understanding language to creating abstract mathematics—with a power budget of only about 20 watts is a feat that cannot be explained by classical Turing machine models.

3. A potential counter-argument might suggest that the 50 Joule limit is an arbitrary threshold and that a sufficiently powerful engineered cooling system, such as a next-generation dilution refrigerator, could handle this thermal load.

4. This means the Feynman protocol performed a computation approximately 50 times longer while consuming only about 8% of the total energy, representing an efficiency improvement of more than two orders of magnitude in this direct comparison.

5. Biological quantum processing, if it exists, must contend with a 310 Kelvin environment, yet achieve coherence on cognitive timescales measured in milliseconds.

6. High spin polarization measurements, often exceeding 60%, have been consistently observed in non-magnetic organic molecules at room temperature, a result that cannot be explained by conventional spin-orbit coupling theories for light elements (Naaman & Waldeck, 2015).

How it is done

1. Through a stochastic master equation simulation, we compare a high-forcing “Shor” protocol against a low-forcing “Feynman” protocol.

2. Our stochastic simulation provides quantitative evidence of this thermodynamic runaway, validating the existence of the “Thermodynamic Wall.” The model for the “Shor Protocol,” which simulates an active control strategy with a high forcing parameter ($\delta=50.0$), shows a quadratic scaling of heat dissipation with the control amplitude.

3. This “analog” path was the dominant paradigm until 1994, when Shor’s discovery of an efficient factorization algorithm recast the quantum computer as a “digital” calculator for abstract number theory.

4. This injected energy is inevitably dissipated as heat, leading to the entropy production that characterizes the “Forced” protocol.

What would falsify it

1. This work refutes the “Myth of Specialization” by invoking the AQC equivalence theorem, which proves that Hamiltonian-based systems (“Feynman Matter”) are computationally universal.

   from Thermodynamic

2. This thesis refutes the notion of a deep physical split, re-contextualizing the bifurcation as a symptom of the entropic disease described in the previous section (Quni-Gudzinas, 2025c).

   from 1.2 The Feynman-Shor

3. This refutes the notion that the Feynman path is limited to “special-purpose” simulation and re-establishes it as a thermodynamically superior path to general-purpose computation.

Where the claim stops

1. Our current SME framework relies on several simplifying assumptions that, while necessary for tractability, restrict the generalizability of quantitative predictions to real-world complexities.

   from 5.6 Limitations and Future

2. These limitations, drawn from a critical self-assessment, do not invalidate the qualitative conclusions but rather define the critical path for the next phase of research.

3. The primary limitation lies in the “White Noise Approximation” for the thermal bath (Quni-Gudzinas, 2025a).
