The theory of quantum consciousness proposes that quantum phenomena occurring in the brain, such as superposition or entanglement, may be essential components of conscious experience and thought processes. This theory states that quantum states in the neurons of the brain could explain how various sensations and thoughts are perceived and integrated into a coherent conscious experience. Although quantum consciousness is still an unconfirmed and widely debated field of science, it opens up new perspectives not only in quantum physics, but also in neuroscience and philosophy, exploring the mystery of consciousness.
