Unfortunately, unitary quantum gates, the main ingredient of quantum computing [2], are not compatible with irreversible biological systems which are effectively non-unitary. That is why Penrose and Hameroff [3, 4] have suggested and Hagan et al. have theoretically confirmed [5] that long lasting coherent states may exist in microtubuli of the neuron’s cytoskeleton. Furthermore, it has been argued that microtubular processes are linked to consciousness because of how they are affected by anaesthetics [6]. However, no experimental evidence exists so far that could connect consciousness to quantum computing. Here, we used magnetic resonance imaging (MRI) to study long-range quantum coherence in the human brain. We were surprised to find that the cardiac pressure pulse evoked zero-spin echoes (ZSEs) in brain parenchyma. The ZSE signals, which are thought to be generated by long-range intermolecular zero-quantum coherence (iZQC) [7], were much higher than expected. In contrast, single quantum coherence (SQC) imaging, which is also indirectly related to iZQC, was not affected. These findings suggest that we observed a non-classical effect originated from a small subdomain of the parenchyma. This evoked quantum effect was directly connected to consciousness as only sporadic ZSE signals were detected during sleep while a loss of the evoked quantum effect would probably always result in unconsciousness. We concluded, that the observed quantum phenomenon must be a necessity for consciousness. Our findings are unexpected but in line with recent biological research [8–12] and further theoretical results [13, 14], which have been shown that quantum coherence and entanglement can play an important role in biology.
