⚡ Quantum Brief
A new theoretical framework introduces coherence dispersion (Δc), quantifying how quantum coherence distributes across off-diagonal elements of arbitrary quantum states, revealing it peaks at intermediate entropy levels—a hallmark of complex systems. The study applies this model to out-of-equilibrium biological systems, showing even minimal quantum coherence could influence cellular energetics, particularly ATP-ADP energy conversion (30.5 kJ/mol). Temperature ranges where Δc is maximized align with those sustaining unicellular life, suggesting quantum effects may subtly optimize biological energy processes without requiring high coherence levels. This work bridges quantum physics and biology by demonstrating how fundamental quantum properties might shape life’s operational temperature limits, using a simplified cellular energy model. The findings imply quantum coherence—often overlooked in biology—could play a functional role in basic metabolic processes, offering new avenues for quantum-biology research.

Quantum Physics arXiv:2512.12342 (quant-ph) [Submitted on 13 Dec 2025] Title:Coherence Dispersion and Temperature Scales in a Quantum-Biology Toy Model Authors:Fernando Parisio View a PDF of the paper titled Coherence Dispersion and Temperature Scales in a Quantum-Biology Toy Model, by Fernando Parisio View PDF HTML (experimental) Abstract:In this work, we investigate how quantum coherence can scatter among the several off-diagonal elements of an arbitrary quantum state, defining coherence dispersion ($\Delta_{\rm c}$). It turns out that this easily computable quantity is maximized for intermediate values of an appropriate entropy, a prevalent signature of complexity quantifiers across different fields, from linguistics and information science to evolutionary biology. By focusing on out-of-equilibrium systems, we use the developed framework to address a simplified model of cellular energetics, involving remanent coherence. Within the context of this model, the precise energy of 30.5 kJ/mol (the yield of ATP-ADP conversion) causes the temperature range where $\Delta_{\rm c}$ is maximized to be compatible with temperatures for which unicellular life is reported to exist. Low levels of coherence suffice to support this conclusion.
