DNA as a Quantum Computer: resonant states of electron and hole pairs in DNA.

An interesting article appeared in Nature Scientific Reports (May 2024, DOI 10.1038/s41598-024-62539-5). To summarize, the article boldly claims that DNA could function as a perfect quantum computer due to its molecular structure and quantum properties. It compares the behavior of DNA's aromatic bases and hydrogen bonds to qubits in quantum computing. DNA meets the DiVincenzo criteria for quantum computing, allowing for multiple qubits, initialization, and gate operations with high fidelity. 

I'm not familiar with the quantum physics of DNA and cannot follow the specific details in the paper. But I read that while quantum effects may be present in DNA, they are unlikely to be significant enough to support complex computations. I think building a practical quantum computer based on DNA faces significant challenges. Maintaining coherence (the delicate quantum states necessary for computation) in biological systems like DNA is extremely difficult due to environmental noise and decoherence.
