The brain is a quantum computer that processes sensual input with remarkable acuity, visual sensitivity to 1 photon, skin feeling the difference in 1 billionth of an atmospheric pressure variation and the fingers can feel object as small as 3 nanometers. Our comprehension of Quantum physics is now at the same point that our understanding of electromagnetism was two hundred years ago.  Quantum computers are being built but the quantum mind is wide open for exploration.  Simple things like gaining complete control of yourself are first order easy.  Gaining control of probabilities is more complex but do able.  Becoming a fully aware quantum consciousness is the goal, as was achieved the ancient Polynesian navigator-poets.  The achievement of this goal equates to complete immortality and freedom.  At this point life as it is commonly known becomes essentially meaningless. As stated in the Heart Sutra and alluded to in the first chapter of the Tao Te Ching as the dark secret within a secret which is the gate to true knowledge.
