“Quantum consciousness” is a term some people use to explain consciousness using quantum physics. Others use the term to define consciousness as existing outside matter, energy, space, and time. The word “quantum” imparts a magical charisma to any area to which it is applied, such as products showing dramatic increases in quality or power, EMF protection devices, and even nutritional products. This charisma might give us a possible definition for quantum consciousness.
A more exciting definition could be that quantum consciousness is consciousness at a much higher, more intense level that focuses attention fully in the present moment — the experience of enlightenment. Drugs such as DMT or LSD might give temporary, distorted windows into this experience, but the path of self-discovery is the most natural and satisfying, and it always gets better.
