Building a quantum computer from living parts (FMO proteins)

Click For Summary
SUMMARY

The discussion centers on the feasibility of constructing a quantum computer using FMO proteins found in photosynthetic complexes. These proteins can maintain quantum entanglement for several picoseconds, presenting a potential solution to the decoherence challenge in quantum computing. However, the practicality of utilizing these organic molecules for computational purposes remains uncertain, as picoseconds are relatively brief for computational tasks compared to other quantum systems like trapped ions.

The most serious challenge to engineering a quantum computer is protecting it from decoherence. But FMO proteins in photosynthetic complexes can exhibit entanglement for a few picoseconds as reported here and here, among other places. So would it be possible to build a working, useful quantum computer using these proteins? Could this help fix decoherence issues? I don't have a good feeling for how practical this would be.

Picoseconds are long for organic molecules, but short for computations - individual ions in traps or similar quantum objects should be better.
