MERLIN SCIENCE — Posner Molecule's Broken Symmetry Limits Its Quantum Qubit Viability — E8 Intelligence Research

Here is the narration for the MERLIN SCIENCE video. --- The finding, in one clean sentence: The Posner molecule, long speculated to be a biological quantum processor, does not possess the full octahedral symmetry in its dynamical ensemble that the idealized crystal structure suggests, and this broken symmetry fundamentally limits its viability as a qubit. For context, the field of quantum biology has been tantalized by the idea that nuclear spins on phosphorus atoms in a calcium-phosphate cluster could maintain entanglement long enough to perform computational-like tasks in the brain. The Posner molecule, with its six phosphorus-31 nuclei, each a spin-1/2, offers a 64-dimensional Hilbert space. The hope was that its near-octahedral symmetry—a point group of order 48—would provide a decoherence-protected subspace, a set of singlet states immune to environmental noise. Here is the mechanism you should evaluate. The paper, arXiv:2108.08822v2, shows that when you consider the actual dy Author: Andrew Stewart Caldin, Independent Researcher, UK.
