How Long Do Quantum Effects Last in Biological Processes?

In summary, some biological phenomena, such as photosynthesis, quantum smell, and the sensation of Earth's magnetic field by the European Robin, have been found to have a quantum background. The coherence times of these phenomena are very short, as decoherence occurs quickly at the classical level. These phenomena are similar to transistors in that they rely on quantum mechanics for explanation, specifically the physics of quasi particles. A paper by Maximilian Schlosshauer provides experimental evidence and consistency for the use of minimal no-collapse quantum mechanics in understanding these phenomena.

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.

FAQ: How Long Do Quantum Effects Last in Biological Processes?

What is coherence time in biology?

Coherence time in biology refers to the duration for which a biological system remains in a state of coherence, meaning that the components of the system are synchronized and working together in a coordinated manner.

How is coherence time measured in biology?

Coherence time is typically measured through techniques such as time-resolved fluorescence spectroscopy or two-dimensional electronic spectroscopy, which involve monitoring the dynamics of molecular interactions and energy transfer within a biological system.

What factors affect coherence time in biology?

Several factors can affect coherence time in biology, including temperature, pH levels, and the presence of specific molecules or proteins that can either enhance or disrupt the coherence of the system.

Why is coherence time important in biology?

Coherence time is important in biology because it plays a crucial role in many biological processes, such as photosynthesis and energy transfer, which rely on the coordination and synchronization of molecular interactions to function effectively.

How can coherence time be optimized in biology?

Optimizing coherence time in biology can involve manipulating environmental factors, such as temperature and pH, as well as altering the structure and composition of biological systems through genetic engineering or other techniques to enhance their coherence and improve their functioning.
