One of the great joys in life is to be shown a grand-scale concept that one never saw coming. We knew that entanglement can occur between not just two, but many particles, but the idea that it’s due not to some mysterious link, but instead to an inherent property of the particle itself is an exciting notion, one that opens up a range of possibilities impossible to foresee.
But there’s still a few flies in the ointment. First off, the paper describes this function only as applied to qubits. Entanglement has been observed in compounds on the molecular level and attempts are being made to observe entanglement of complex molecules, and I am doubtful that the entanglement-as-inherent-property concept could be applied to complex molecules. This conflict would become even more problematic when applied to the rising discipline of quantum biology.
That being said, such examples still may not disprove the inherent-property theory since there are certainly different forms of entanglement, and inherent-property may only apply to the most basic of particles.
Again, thank you so much for your article!
