The most controversial suggestion to emerge concerning the action of homeopathic medicines in recent years is that they act non-locally, through ‘quantum entanglement’. Quantum mechanics (QM) accurately predicts counterintuitive phenomena including quantum entanglement. Quantum entanglement occurs when subatomic particles are generated or interact in such a way that the quantum state of each particle cannot be described independently. Instead, the quantum state of the whole system must be considered.

The implication is that subatomic particles with a common origin remain ‘entangled’, so that anything done to one particle instantaneously influences the other entangled particles, even when they have travelled enormous distances from their common origin. This was famously described as ‘spooky action at a distance’, by Albert Einstein, who never fully accepted quantum theory. But such entanglement has been repeatedly experimentally demonstrated at a microscopic scale.
