THERMODYNAMIC AND TOPOLOGICAL CONSTRAINTS ON BIOLOGICAL QUANTUM PROCESSING

In the paper's words

This study establishes a rigorous quantitative boundary between engineered quantum systems and biological matter, defined by the thermodynamic cost of information protection. By benchmarking the 2025 Google “Willow” superconducting processor—which requires cryogenic isolation (20 mK) and active error correction to achieve a logical coherence time of 291 μs—against the biological requirement of 25 ms at 310 K, we identify a protection deficit of approximately 10¹2. We demonstrate that standard gravitational collapse models (Orch OR) are falsified by radiative constraints (R₀ limits) from underground experiments.

The abstract, verbatim, and its opening sentence is the claim. Every line below is quoted from the text.

Numbers it reports

1. Crucially, the logical error rate per cycle was suppressed to approximately 0.143 percent.

2. The exchange rate remains valid: if the Willow processor needs 101 physical qubits and 20 mK to get 291 microseconds, and biology needs to get 25 milliseconds at 310 K, the gap in efficiency must be explained.

3. The simulation for the “Spintronic Wire” model shows that even with a high polarization efficiency of 99%, the coherence time of the electron is only extended to the nanosecond or sub-nanosecond range ($10^{-10}$ seconds).

4. At a physiological temperature of 310 Kelvin, the thermal energy acts as a relentless chaotic driver, creating a noise floor that is twelve orders of magnitude higher than the energy levels associated with delicate quantum phases.

   from 4.1 Thermal Baseline

5. Even with an optimistic polarization efficiency of 99.99%, the protection factor is limited to roughly $10^4$.

   from 4.5 Transport Limit

6. While this is a 10,000x improvement over baseline, it is still $10^8$ times too short for the cognitive target.

   from 4.5 Transport Limit

How it is done

1. For a biological cell, which operates on a limited budget of adenosine triphosphate, the active approach is metabolically ruinous.

   from 1.1 Epistemic Boundary

2. The Google Willow processor represents the current apex of human achievement in the stabilization of quantum information, creating a precise exchange rate between physical resources and logical coherence.

   from 1.2 Engineering Benchmark

3. This approach acknowledges that physical qubits will inevitably decohere, and instead of trying to make a perfect physical qubit, it builds a perfect logical qubit out of many imperfect ones.

   from 2.2 Active Error Correction

4. The search for spontaneous radiation found no excess X-rays, which places a lower bound on the smear radius.

   from 2.3 Radiative Collapse Limits

What would falsify it

1. We demonstrate that standard gravitational collapse models (Orch OR) are falsified by radiative constraints ($R_0$ limits) from underground experiments.

   from THERMODYNAMIC

2. This quantitative evidence serves as a definitive falsification of any biological model that proposes an analogue to the surface code.

   from 1.1 Epistemic Boundary

3. The hypothesis that gravity induces the collapse of the wavefunction—the core of the Orch OR theory—makes a specific physical prediction: the reduction of the quantum state involves a rearrangement of mass density that should have observable thermodynamic consequences.

Where the claim stops

1. By benchmarking the 2025 Google “Willow” superconducting processor—which requires cryogenic isolation (20 mK) and active error correction to achieve a logical coherence time of 291 μs—against the biological requirement of 25 ms at 310 K, we identify a protection deficit of approximately $10^{12}$.

   from THERMODYNAMIC

2. However, as quantum technology matured from the experimental physics of the 2010s to the industrial engineering of the 2020s, the nature of the critique evolved.

   from 1.1 Epistemic Boundary

3. This might involve topological phases of matter where local perturbations cannot destroy global information, or symmetry-protected subspaces where the interaction with the environment is forbidden by conservation laws.
