Quantum physics, currently seen as a further refinement in the description of nature, does not only describe elementary microphysics but applies to classical or macro-physical (Newtonian) phenomena as well. Hence the human brain and its mental aspects are associated to classical brain physiology and are also part of a quantum physical universe. Most neurobiologists considered QM mind theories irrelevant to understand brain/mind processes (e.g. Edelman and Tononi, 2000; Koch and Hepp, 2006). However, there is no single theory on QM brain/mind theory. In fact a spectrum of more or less independent models have been proposed, that all have their intrinsic potentials and problems. The elements of quantum physics discussed here are summarized in Table 1 and 2; details of the various QM theories have been described elsewhere (Meijer, 2012; Meijer and Korf, 2013). Some QM mind options assume some sort of space-time multidimensionality, i.e there are more than the four conventional space-time dimensions. Other options assume that one or more extra dimensions are associated with a mental attribute or that the individual mind is (partly) an expression of a universal mind through holonomic communication with quantum fields (Fig.1). The latter idea has led to holographic (holonomic) theories (Pribram 1986, 2011). The human brain is then conceived as an interfacing organ that not only produces mind and consciousness but also receives information. The brain or parts of the brain are conceived as an interference hologram of incoming data and already existing data (a “personal universe”). If properly exposed (“analyzed”), information about the outer world can be distilled. In neurobiological terms, the existing data is equivalent to the subject’s memory, whereas the “analyzer” is cerebral electrophysiology. Bohm hypothesized that additional dimensions are necessary to describe QM interference processes, thereby circumventing probabilistic theories and consciousness-induced collapse of the wave function. In this theory, the universe is a giant superposition of waves, representing an unbroken wholeness, of which the human brain is a part (Bohm, 1990). Accordingly, the individual mind or consciousness is an inherent property of all matter (and energy), and as such being part, or rather an expression, of this universal quantum field. The apparently diffuse time/space localization of mental functions argues in favor of an underlying multidimensional space/time reality. Bohm and Hiley (1987) also proposed a two-arrow (bidirectional) time dimension. In this concept the stochastic (or double stochastic) character of quanta is explained by an underlying quantum field: the implicate order. This concept implies entanglement (non-locality) as well. 2 Another hypothesis, having the potential to couple wave information to mental processes, proposes that wave information is transmitted from and into the brain by wave resonance. Through conscious observation they collapse locally to material entities (Stapp 2009; Pessa and Vitiello, 2003; Schwartz et al., 2004). Stapp (2012) argued that this does not represent an interference effect between superposed states (as assumed by Hameroff and Penrose, 1996), but that through environmental de-coherence, super-positions become informative to the brain/organism. A complementary implication of these theories is that mental processes are not necessarily embedded in entropic physical time. In line with this QM idea is that memories are not stored as a temporal sequence, but rather a-temporally. Fig. 1: The hypothesis that the universe and our minds are integral parts of a universal consciousness Some QM mind theories suppose the possible involvement of specific molecules. A spectrum of ions and molecules has been suggested to operate in a quantum manner (Tuszinsky and Woolf 2010). For instance QM theories have been based on micro-tubular proteins (Penrose 1989; Hameroff 2007), proteins involved in synaptic transmission (Beck and Eccles 1992; Beck 2001), including Ca ion-channels (Stapp 2009) and channel proteins instrumental in the initiation and propagation of action potentials (potassium-ion channels, Bernroider and Roy 2004. There is also the hypothesis that synaptic transmission represents a typical (quantum) probability state that becomes critical for an all or none neuronal response (Beck and Eccles 1992; Beck 2001). Attributing non-linear and non-computable characteristics of consciousness, 3 Hameroff and Penrose, 2011, 2013, argue against mechanisms of all or none firing of axonal potentials (Beck and Eccles, 2003). They rather prefer the model of Davia (2010), proposing that consciousness is related to waves traveling in the brain as a uniting life principle on multiple scales. According to some QM mind theories (Woolf and Hameroff, 2001), tunneling was proposed to facilitate membrane/vesicle fusion in neural information processing at the synapse. Kauffman relates quantum processes in the biological matrix of the brain to the emergence of mental processing (Kauffman 2010; Vattay et al. 2012). This theory, mainly based on chromophores detecting photons, assumes that the coherence of some quantum configurations adhered to proteins is stabilized or is maintained by re-coherence. This principle may have guided evolutionary selection of proteins. Accordingly, mind and consciousness are both quantum mechanical and an expression by the classical neural mechanisms. The underlying coherent quantum states provide the potentiality for the collapse to the de-coherent material state, resulting in classical events such as firing neurons, that are at least to some extent, a- causal, i.e. beyond classical determinacy. The quantum system (of the brain) interacts with a quantum environment, the phase information is lost and cannot be reassembled. By entanglement, the quantum coherence in a small region, e.g. the cell or the brain, might have spatial long-range effects (Vattay et al. 2012; Hagan et al. 2002). Kauffman accepts long-lived coherence states in biological molecules at body temperature (now 750 femto-seconds in chlorophyll at 77K) to be potentially enabling parallel problem solving as major challenges for further investigations. The question is also which neurons or neuronal structures are in particular associated to the coherence/de-coherence brain model of consciousness. The question is often put as to why quantum theory should be involved in discussions of consciousness at all, and also as to why it should be treated as something special. In thinking about quantum theory, it is important not to be bullied into viewing it as something weird and peripheral that can be ignored (Atmanspacher, 2011). Unfortunately, this allows the more superficial thinkers to dismiss all theories of quantum consciousness. This sort of practice has recently been criticized as ‘pseudoscepticism’, a parallel form to pseudoscience. Pseudo- skepticism (see Wikipedia) similarly uses denunciation in the name of science or scientific affiliation without citing any evidence or possible experimentation to establish this criticism, (see Utts and Josephson, 1996). The features of quantum theory that make it special and also possibly relevant to consciousness can be summarized as follows: 1.) Quantum theory describes the fundamental level of energy and matter. In contrast to higher levels, the quantum level has aspects, such as mass, charge and spin that are given properties of the universe, not capable of further reduction or explanation. In quantum theories of consciousness, it is suggested that consciousness is such a fundamental property existing at this level. Some theories are additionally linked to the structure

Heisenberg derived this relation under an additional assumption on quantum measurements that is consistent with the so-called repeatability hypothesis, which was pos- tulated in von Neumann’s measurement theory and supported by Schroedinger and contemporaries. However, the repeatability hypothesis has been abandoned in the modern quantum measurement theory, originated by Davies and Lewis in the 1970’s. Later, the universal validity of Heisenberg’s uncertainty principle was questioned typically in a debate on the sensitivity limit to gravitational wave detectors in the 1980’s. A universally valid form of the error-disturbance relation was derived in the modern framework for general quantum measurements by the present speaker in 2003. Since then we have experienced a considerable progress in theoretical and experimental studies of universally valid reformulation of Heisenberg’s uncertainty principle.

CARLTON Stanford ~nio'ersity,Stanford, USA Accepted September 1986 Image processing in the visual system is described utilizing some basic neurophysiological data. We propose that both sensory and cognitive operations address features already conjoined in critical receptive fields. As both sensory perception and further processing stages are critically dependent upon movement, the theory emphasizes sensory-motor reciprocity in imaging and in object perception. 'If we could find a convenient way of showing not merely the amplitudes of the envelopes but the actual oscillations of the array of resonators, we would have a notation (cf. Gabor 1946) of even greater generality and flexibility, one that would reduce under certain idealizing assumptions to the spectrum and under others to the wave form . The analogy .

    Theoretical UNITY CONSCIOUSNESS: A QUANTUM BIOMECHANICAL FOUNDATION Thomas E. Beck, Ph.D. & Janet E. Colli, Ph.D. ABSTRACT Citing research in consciousness, quantum physics, biophysics and cosmology, we propose the collective amplification of quantum effects as the basis for scientifically describing Kundalini awakening, and the higher-order, emergent phenomenon of Unity consciousness, Such alterations of consciousness have their origin in quantum-scale processes, such as self-induced transparency, superradiance, superpositions, quantum tunneling, and Bose-Einstein condensa­ tion, Microtubules are considered to be key components in non-local, quantum processes critical to human consciousness, We postulate that bundles of fibers (neural cells), each containing numerous microtubule "lasers" acting in unison, collectively result in a massive surge of light energy to the brain, The sudden onset and radically altered nature of such states are consis­ tent with a model based on the activation of a laser.

  • Arxiv:1107.3800V2 [Physics.Hist-Ph] 30 Nov 2011 Uzigfaue,Sc Stemdfiaino Elt Ythe by Reality of Ment
    Quantum magic: A skeptical perspective Giorgio Torrieri FIAS, J.W. Goethe Universit¨at, Frankfurt A.M., Germany torrieri@fias.uni-frankfurt.de Quantum mechanics (QM) has attracted a considerable amount of mysticism, in public opinion and even among academic researches, due to some of its conceptually puzzling features, such as the modification of reality by the observer and entangle- ment. We argue that many popular ”quantum paradoxes” stem from a confusion be- tween mathematical formalism and physics; We demonstrate this by explaining how the paradoxes go away once a different formalism, usually inconvenient to perform calculations, is used. we argue that some modern developments, well-studied in the research literature but generally overlooked by both popular science and teaching- level literature, make quantum mechanics (that is, ”canonical” QM, not extensions of it) less conceptually problematic than it looks at first sight. When all this is looked at together, most “puzzles” of QM are not much different from the well-known paradoxes from probability theory. Consequently, “explanations of QM” involving physical action of consciousness or an infinity of universes are ontologically unnecessary arXiv:1107.3800v2 [physics.hist-ph] 30 Nov 2011 2 I. INTRODUCTION All the way from its origins, the theory of quantum mechanics (QM) [1] has enjoyed a resounding experimental success, but has elicited unease regarding its philosophical impli- cations, and place as a scientific theory. A lot of research effort on the part of distinguished scientists [2–4] (founders of QM among them! [5–8]) has gone into “interpreting” quantum mechanics. This effort has produced quite a few candidates for interpretation, ranging from the sensible but ambiguous Copenhagen interpretation (“quantum variables only refer to what can be known to us, rather than any objective reality”) esoteric ideas (such as “many universes” and a role of consciousness in quantum physics), less ontologically troublesome extensions (“hidden variables”) as well as quite a few “paradoxes”.

  • What Is Consciousness? Artificial Intelligence, Real Intelligence, Quantum Mind, and Qualia
    What Is Consciousness? Artificial Intelligence, Real Intelligence, Quantum Mind, And Qualia Stuart A. Kauffman1 and Andrea Roli2,3 1Institute for Systems Biology, Seattle, USA 2Department of Computer Science and Engineering, Campus of Cesena, Alma Mater Studiorum Universit`adi Bologna 3European Centre for Living Technology, Venezia, Italy July 24, 2021 Abstract We approach the question \What is Consciousness?" in a new way, not as Descartes' \systematic doubt", but as how organisms find their way in their world. Finding one's way involves finding possible uses of features of the world that might be beneficial or avoiding those that might be harmful. \Possible uses of X to accom- plish Y" are “Affordances”. The number of uses of X is indefinite (or unknown), the different uses are unordered and are not deducible from one another. All biological adaptations are either affordances seized by heritable variation and selection or, far faster, by the organism acting in its world finding uses of X to accomplish Y. Based on this, we reach rather astonishing conclusions: (1) Artificial General Intelligence based on Universal Turing Machines (UTMs) is not possible, since UTMs cannot “find” novel affordances. (2) Brain-mind is not purely classical physics for no classi- cal physics system can be an analogue computer whose dynamical behavior can be isomorphic to \possible uses". (3) Brain mind must be partly quantum|supported by increasing evidence at 6.0 sigma to 7.3 Sigma. (4) Based on Heisenberg's interpre- tation of the quantum state as \Potentia" converted to \Actuals" by Measurement, a natural hypothesis is that mind actualizes Potentia.

  • Understanding Human Consciousness: Theory and Application
    o Journal of Experiential Psychotherapy, vol. 21, n 2 (82) June 2018 Understanding Human Consciousness: Theory and Application Maretha Prinsloo, PhD*i *Cognadev, UK “Consciousness implies awareness: subjective, phenomenal experience of internal and external worlds... Our views of reality, of the universe, of ourselves depend on consciousness. Consciousness defines our existence.” (Hameroff & Penrose, 2014, p. 39) Abstract Introduction: The study of consciousness attracts the attention of psychologists, philosophers and scientists. It is, however, mostly dealt with in a descriptive and speculative manner, without explaining the nature of the subjective experience and the dynamics involved. Objectives: This article aims to provide a brief overview of prominent philosophical, psychological, sociological and quantum physics perspectives on consciousness. The practical implications of consciousness theory are also addressed. Methods: Literature review. Results: From a social sciences point of view, Gebser’s Structure of Human Consciousness model, Clare Graves’s Spiral Dynamics (SD) model and Ken Wilber’s Integral AQAL model are briefly discussed to understand the concept of levels of consciousness and to differentiate between the developmental themes which characterise each of these levels. This is followed by a description of scientific theories and findings. Here the work of prominent philosophers of science, including Dennett and Laszlo, is briefly explored. Neurological and quantum physics discoveries, including the work of Bohm, Pribram, McTaggart, Hameroff and Penrose are referred to and the phenomenon of collective consciousness is explained in terms of the physics concepts of quantum nonlocality and entanglement. Next, the application of consciousness theory is addressed within the contexts of societal transformation, leadership, organisational development, organisational culture and education.

  • Weak Measurements, the Energy-Momentum Tensor and the Bohm Approach Robert Flack and Basil J
    6 Weak Measurements, the Energy-Momentum Tensor and the Bohm Approach Robert Flack and Basil J. Hiley Abstract μ In this paper we show how the weak values, x(t)|P |ψ(t0)/x(t)|ψ(t0), are related to the T 0μ(x, t) component of the energy-momentum tensor. This enables the local energy and momentum to be measured using weak measurement techniques. We also show how the Bohm energy and momentum are related to T 0μ(x, t) and there- fore it follows that these quantities can also be measured using the same methods. Thus the Bohm ‘trajectories’ can be empirically determined as was shown by Kocis et al in the case of photons. Because of the difficulties with the notion of a photon trajectory, we argue the case for determining experimentally similar trajectories for atoms where a trajectory does not cause these particular difficulties. 6.1 Introduction The notion of weak measurements introduced by Aharonov, Albert and Vaidman (1988,1990) has opened up a radically new way of exploring quantum phenomena. In contrast to the strong measurement (von Neumann 1955), which involves the collapse of the wave function, a weak measurement induces a more subtle phase change which does not involve any collapse. This phase change can then be ampli- fied and revealed in a subsequent strong measurement of a complementary oper- ator that does not commute with the operator being measured. This amplification explains why it is possible for the result of a weak spin measurement of a spin-1/2 atom to be magnified by a factor of 100 (Aharonov et al.

  • Weak Measurement and Feedback in Superconducting Quantum Circuits
    1 Weak Measurement and Feedback in Superconducting Quantum Circuits K. W. Murch, R. Vijay, and I. Siddiqi 1 Department of Physics, Washington University, St. Louis, MO, USA [email protected] 2 Tata Institute of Fundamental Research, Mumbai, India [email protected] 3 Quantum Nanoelectronics Laboratory, Department of Physics, University of California, Berkeley, CA, USA [email protected] Abstract. We describe the implementation of weak quantum measurements in su- perconducting qubits, focusing specifically on transmon type devices in the circuit quantum electrodynamics architecture. To access this regime, the readout cavity is probed with on average a single microwave photon. Such low-level signals are detected using near quantum-noise-limited superconducting parametric amplifiers. Weak measurements yield partial information about the quantum state, and corre- spondingly do not completely project the qubit into an eigenstate. As such, we use the measurement record to either sequentially reconstruct the quantum state at a given time, yielding a quantum trajectory, or to close a direct quantum feedback loop, stabilizing Rabi oscillations indefinitely. Measurement-based feedback routines are commonplace in modern elec- tronics, including the thermostats regulating the temperature in our homes to sophisticated motion stabilization hardware needed for the autonomous oper- ation of aircraft. The basic elements present in such classical feedback loops include a sensor element which provides information to a controller, which in turn steers the system of interest toward a desired target. In this paradigm, the act of sensing itself does not a priori perturb the system in a significant way. Moreover, extracting more or less information during the measurement process does not factor into the control algorithm.
