SUMMARY

The discussion centers on the role of quantum effects in biological processes, specifically highlighting phenomena such as photosynthesis, quantum smell as proposed by Luca Turin, and the European Robin's ability to sense the Earth's magnetic field. The coherence times of these quantum effects are notably short, with decoherence occurring rapidly at the classical level of biology. The underlying principles resemble those of transistors, which, while classical objects, rely on quantum mechanics for their functionality, particularly through the physics of quasi-particles like holes. The paper by Maximilian Schlosshauer provides empirical consistency and experimental motivation for these observations.

Not long ago some biological phenomena were found that have quantum background. These are photosyntesis, quantum smell (Luca Turin), sensation of Earth magnetic field by European Robin etc.

What are coherence times of these phenomena?

Decoherence happens very very quickly at the classical level of biology.

What is going on here is similar to why transistors work - its a classical object - but it depends on QM to explain it - in that particular case the physics of quasi particles like holes.

Thanks
