Organisms respond to quantum information

AI Thread Summary
Biological systems are sensitive not only to light but also to phase information, which could indicate a self-designed sensitivity in these organisms. Recent research demonstrates that quantum effects, particularly phase manipulation, can influence molecular reactions, such as retinal isomerization in bacteriorhodopsin, enhancing efficiency by up to 20%. This raises intriguing questions about whether similar mechanisms might be utilized in human vision, as bacteriorhodopsin is related to the opsin molecules in our retinas. The potential for organisms to exploit phase information in light suggests a deeper connection between quantum mechanics and biological processes. Further research is needed to explore these possibilities in both bacterial and human systems.

“We’ve known for a long time that biological systems are sensitive to light but not necessarily that they are sensitive to the phase information that may or may not be present in light,” explains Prokhorenko. “This finding opens up how we perceive biological systems and raises new questions such as, have biological systems designed themselves to be sensitive to phase information? What other roles do quantum effects play in nature?”

And:

Because of the wave-particle duality inherent in quantum mechanics, different states along the pathway of a molecular rearrangement can interfere with each other like vibrations on a string. The phases and amplitudes of spectral components in light pulses that initiate photochemical reactions can now be created that can steer small molecules along distinct reaction trajectories by inducing constructive or destructive wave interference among states. Prokhorenko et al. show that this approach can modulate the efficiency of retinal isomerization in the protein bacteriorhodopsin (a rearrangement closely related to the vision response) by as much as 20% in either direction. The extent of modulation is remarkable in light of the many degrees of freedom in the protein environment that might be expected to randomize the wave phases

So they have used phase information to control a biological process, but how about the organisms themselves: do they use light in the same way?

They also mention 'the vision response', is that our eyes? Do our eyes/brain use phase information to create our vision?

The bactrhodopsin molecule they mention is bacterial, but it is apparently a chemical relative of the opsin molecules that mediate our vision in our retinas. So they are suggesting that if bacteria can do it, maybe our eyes can do it, or be made to do it, too. Obviously that will be a subject of further research.
