This template must be substituted. Quantum mysticism is the claim that the laws of quantum mechanics incorporate mystical ideas similar to those found in certain religious traditions or New Age beliefs. It is descended from the measurement problem – the seemingly special role which observers play in quantum mechanics. The related term quantum quackery has been used pejoratively by skeptics to discount claims that quantum theory might support mystical beliefs, while quantum mysticism has been used as a more neutral description of ideas that blend the ideas of eastern mysticism and quantum physics.

The laws of quantum physics allow by calculation the prediction of observables, which can be tested in independently repeated experiments to a very high precision. This is a property shared with all other physical theories, but not with mystical beliefs. However, Ken Wilber asserts that meditation with the aim of experiencing higher consciousness may be regarded an experimental science (as it was and is regarded by some Buddhist sects).

Parallels with mysticism were first drawn by the founders of quantum mechanics, most notably Erwin Schrödinger, Werner Heisenberg, Wolfgang Pauli, Niels Bohr, and Eugene Wigner. Nevertheless, critics such as science fiction writer Greg Egan and author Margaret Wertheim, along with many scientists, have opined that quantum mysticism is a hijacking of quantum physics by ill-informed purveyors of pseudo-science.

History

In many mystical traditions, the conscious mind is seen as a separate entity, existing in a realm not described by physical law. Some people claim that this idea gains support from the description of the physical world provided by quantum mechanics.

The reason is that quantum mechanics requires interpretation before it describes the experience of an observer. While particles and fields are described by a wavefunction, the results of observations are described by classical information which tells you the result. The information about observations is not in the wavefunction, but is additional random data. The wavefunction only gives the probability of getting different outcomes, and it only turns into a probability during the act of measurement.

The nature of observation has often been a point of contention in quantum mechanics, because quantum mechanics describes the experiences of observers with different numbers than it uses to describe material objects. With the notable exceptions of Louis DeBroglie, Max von Laue, Erwin Schrödinger and Albert Einstein, who believed that quantum mechanics was a statistical approximation to a deeper reality which is deterministic, most of the founders of quantum mechanics believed that this problem is purely philosophical. Eugene Wigner went further, and explicitly identified it as a quantum version of the mind-body problem.

The observer in classical mechanics and pre-quantum mechanic philosophy

In classical mechanics the world is measurable, the measurements are independent of what they measure, and determinism is an intrinsic assumption. Given the initial positions and velocities of a collection of the basic particles, and it was expected that the future of those particles could one day be predicted perfectly. When these assumptions are applied to an observer the conclusion is with enough information the entire future behavior of the of the observer can be predicted.

The introduction of quantum mechanics change this by making the observer and the measurement an intrinsic part of the world. Yet the problem remained how to reconcile a world that appears classical on the macroscopic scale yet is built out of matter governed by quantum mechanics. The "measurement problem deals with the transition from a quantum world, described by essentially arbitrary linear superpositions of state vectors, to our perception of “classical” states in the macroscopic world, that is, a comparatively small subset of the states allowed by the quantum-mechanical superposition principle, having only a few, but determinate and robust, properties, such as position, momentum, etc. The question of why and how our experience of a “classical” world emerges from quantum mechanics thus lies at the heart of the foundational problems of quantum theory."

Classical mechanics approaches the world from a deterministic materialistic perspective that divorced or at least distanced it from many pre-quantum mechanic philosophies that hold various dualist perspectives. The juxtaposition of classical everyday experience built against a quantum foundation, among other observations raised by quantum mechanics, provided a new perspective from which to interpret traditional dualist ideas like the mind/body problem within a mainstream scientific framework.

Observation in quantum mechanics

Standard interpretations of quantum mechanics made the question of consciousness more immediate. In the Copenhagen interpretation, the theory can only be used to describe the outcome of observations. What constitutes an "observer" or an "observation" is not directly specified by the theory, and the behavior of a system after observation is completely different than the usual behavior. During observation, the wavefunction describing the system collapses to one of several options, each with a different probability. If there is no observation, this collapse does not occur.

Unlike classical mechanics, in quantum mechanics, there is no naive way of identifying the state of an observer, because the quantum state of an object is described by a wavefunction. A wavefunction description either does not describe observers, or it ends up putting them into superpositions of very different states, like Schrödinger's cat. The quantum mechanical wavefunction spreads out, describing an ever larger superposition of different worlds. An observer observing a superposition can be described by a superposition of different observers seeing different things, but in actual experience, an observer never feels a superposition, but always feels that one of the outcomes has occurred with certainty. This apparent conflict between a wavefunction description and classical experience is called the problem of observation, and it was apparent to the early founders of quantum mechanics. Each one had a different opinion about the resolution:

Albert Einstein, and with him Louis DeBroglie and later David Bohm, believed that quantum mechanics was incomplete, that the wavefunction was only a statistical description of a deeper structure which was deterministic. Einstein saw quantum mechanics as analogous to statistical mechanics, and the wavefunction just a peculiar statistical device for observers who are ignorant of the values of the hidden variables underneath. This point of view makes the extra information not at all mysterious--- the results of observations are simply revealing the values of the hidden variables. In 1964, John Bell realized that local hidden variables set a limit on the degree to which the results of distant experiments can be correlated, a limit which is violated in quantum mechanics. The experimental observation of violations of Bell's inequality showed that the original local hidden variables of Einstein Podolski and Rosen could not be correct. Non-local hidden variables are still a possibility, and David Bohm was able to explicitly formulate a nonlocal theory which reproduces the predictions of quantum mechanics. But nonlocal theories are very arbitrary, and the new variables in Bohm's theory are inaccessible to experiments. So most physicists do not accept hidden variable interpretations as compelling.

Niels Bohr believed that quantum mechanics was a complete description of nature, but that it was simply a language ill suited to describing the world of everyday experience, and that in the human realm experiences were described by classical mechanics and by probability. This point of view, the Copenhagen interpretation, was shared by Max Born and Werner Heisenberg and became the standard view. It requires a demarcation line, a boundary, above which an object would cease to be quantum and would start to be classical. Bohr never specified this line precisely, since he believed that it was not a question of physics, but of pure philosophy. Von Neumann, in his analysis of measurements, interpreted the demarcation line as the point where wave-function collapse occurs, and he showed that within quantum mechanics, the point of collapse is largely arbitrary, past the first incoherent interaction with a complex enough object .

Eugene Wigner reformulated Schrödinger's cat using a conscious observer, Wigner's friend. He concluded that the demarcation line which Bohr refused to specify was at the point of conscious experience. Wigner's position was that the wavefunction collapses because consciousness observes it, placing a non-scientific layer at the foundation of quantum mechanics, a non-scientific layer which could be interpreted as mystical, since it treats conscious observation as a separate ingredient.

Decoherence and modern interpretations

Hugh Everett III proposed an entirely mechanistic interpretation of quantum mechanics that has come to be known as the many-worlds interpretation. In Everett's description, the whole universe is an enormous wavefunction, describing a dizzying multiplying possibility of worlds. In this formalism, observers were to be treated as computers or as any other measuring device, their memories written out on magnetic tape . To understand their experiences, you would focus on the answer which these observers would give to questions asked by an external observer. Everett believed that this line of reasoning showed that any interpretational problems in quantum mechanics were entirely philosophical, because he could show that there was no conflict between deterministic evolution of the wavefunction with the subjective randomness experienced by the observers, when analyzed using the theory itself .

Since the physical description in Everett's picture is the deterministic wavefunction, the issue of interpretation is only relevant when analyzing the experience of an observer. The answer to the question "what does this observer see?" is only ambiguous to the extent that the specification of the observer is imprecise. An observer's state is a particular high dimensional projection of the wavefunction, but not all parts of the wavefunction describe a single observer – only those parts which describe a consistent past of memories. In Everett's picture, the interpretation is a clarification, it tells you which observer you are examining. But the description of the observer is now a major chunk of the description of the world--- it includes a lot of extra information not present in the original wavefunction.

This extra information includes most observable parameters in our universe. For example, if the universe started out perfectly homogeneous and isotropic, the universal wavefunction would still be homogeneous and isotropic. But for any observer, the description would be irregular describing a different pattern of galaxies, stars and planets. The information which specifies the observer specifies the positions of all those stars, the distance to Jupiter, the location of the moon in its orbit, the contents of today's newspaper, etc. None of this is in the universal wavefunction, that object is only a quantum superposition of all possible worlds. Most of the nontrivial information is in the history of past random events.

Everett's approach has been elaborated into a field of study called decoherence, which attempts to identify the way in which classical behaviour emerges from quantum mechanics when the systems become large.

Mystical interpretations

The description of the observer in decoherence approaches, as in the Copenhagen approach, always involves extra information, the information which specifies the outcome of all the random events in the past. This information answers the question "which observer?" in many-worlds, and correspondingly answers the question "what outcomes of past measurements?" in Copenhagen.

The presence of large amounts of additional information has been interpreted as a possibly mystical component associated with consciousness, since it is data which is associated with the observer, not with the matter from which the observer is built. Since this includes most information about the universe, considering the quantum mechanical description to be complete leads to a very jarring reevaluation of the nature of the observer.

Consciousness causes collapse

Main article: Wigner's interpretation of quantum mechanics

"Consciousness causes collapse" is the name of an interpretation of quantum mechanics according to which observation by a conscious observer is the cause of wave function collapse.

The involvement of Consciousness has been summarized as follows:

The rules of quantum mechanics are correct but there is only one system which may be treated with quantum mechanics, namely the entire material world. There exist external observers which cannot be treated within quantum mechanics, namely human (and perhaps animal) minds, which perform measurements on the brain causing wave function collapse.

This interpretation attributes the process of wave function collapse (directly, indirectly, or even partially) to consciousness itself. However, it is not explained by this theory which things have sufficient consciousness to collapse the wave function ("Was the wave function waiting to jump for thousands of millions of years until a single-celled living creature appeared? Or did it have to wait a little longer for some highly qualified measurer - with a PhD?"). Until the Hard problem of consciousness is solved, it is undefined what could or could not have consciousness. It could be that measuring devices might also turn out to be considered conscious by this definition.

Consciousness causes collapse can be seen as a proposed answer to the Wigner's friend thought experiment by asserting that collapse occurs at the first "conscious" observer.

Wigner believed that consciousness is necessary for the collapse process. See Consciousness and measurement. There are several possible ways to explain the Wigner's friend thought experiment, some of which do not require consciousness to be different from physical processes. See, Consciousness and Superposition and Wigner's friend in Many Worlds.

Recent study of quantum decoherence reduces the emphasis on the "macroscopic observer" originally introduced in the language of the Copenhagen interpretation of quantum theory for most systems. Modern scientific discourse has evolved to try to quantify how quantum systems decohere due to their interactions with their surroundings. This provides a unified view which treats neighboring quantum systems, thermal baths and the measurement apparatus on the same footing. Although decoherence gives new insight on how quantum mechanics gives rise to the classical world in general, decoherence is not a philosophy and it does by itself claim to give a resolution to the philosophical aspects of the problem of measurement.

Popularization

These counterintuitive aspects of quantum physics were popularized in the 1970s with Fritjof Capra's The Tao of Physics, in which he explores the parallels between quantum physics and principles in Eastern mystical teachings. This was taken up in the 1980s by Hindutva pseudoscience, which extrapolated on the statements of Vivekananda, claiming that "the conclusions of modern science are the very conclusions the Vedanta reached ages ago". It conflated concepts from physics like gravitation, electricity, magnetism and other forces with the mystical Vedantic notion of Prana.

In 1990 Robert Anton Wilson wrote a book called Quantum Psychology which explains Timothy Leary’s Eight Circuit Model of Consciousness in terms of quantum mysticism.

The 2004 film What the Bleep Do We Know!? made controversial use of ideas about quantum mechanics, among other sciences, in a New Age context.

Theories of quantum mind have given rise to concepts like quantum meditation, positing a scientific basis for meditation practices not supported by mainstream science. Among these is quantum healing, which claims that through quantum mechanical effects, the mind can heal the body. Quantum healing invokes quantum entanglement and the observer effect to argue that the consciousness of a healer could impact the body of another person. There are several contemporary new-age practices in this category, including Matrix Energetics, Quantum-Touch, and Quantum Energetics.

Rejections by physicists and mystics

Several of the founders of quantum physics were interested in the link between quantum mechanics and mysticism, including Niels Bohr, Werner Heisenberg, Eugene Wigner and Erwin Schrödinger. They felt that quantum mechanics required a subtle reexamining of the role of conscious experience in the physical world.

Unlike them, the British physicist Sir Arthur Eddington rejected the notion that mysticism and physics had anything more than a metaphorical relationship. Eddington explained the temptation and why he felt it should be avoided: "We should suspect an intention to reduce God to a system of differential equations. That fiasco at any rate must be avoided. However much the ramifications of physics may be extended by further scientific discovery, they cannot from their very nature the background in which they have their being."

Responding to results of violations of Bell's inequality, results which cast doubt on hidden-variable interpretations, physicist Heinz Pagels explicitly rejected any link between the supernatural phenomenon often associated with mysticism and quantum mechanics, writing:

"Some recent advocates of Bell's work when confronted with Bell's inequality have gone on to claim that telepathy is verified or the mystical notion that all parts of the universe are instantaneously interconnected is vindicated. Others assert that this implies communication faster than the speed of light. That is rubbish; the quantum theory and Bell's inequality imply nothing of this kind. Individuals who make such claims have substituted a wish-fulfilling fantasy for understanding. If we closely examine Bell's experiment we will see a bit of sleight of hand by the God that plays dice which rules out actual nonlocal influences. Just as we think we have captured a really weird beast--like acausal influences--it slips out of our grasp. The slippery property of quantum reality is again manifested."

Likewise some mystics doubt that quantum physics and mysticism describe the same realm. Tom Huston, in a review on the quantum mystical film What the Bleep Do We Know!? for What is Enlightenment? Magazine wrote:

"Quantum physics deals with the abstract, symbolic analysis of the physical world—space, time, matter, and energy—even down to the subtlest level, the quantum vacuum. Mysticism deals with the direct apprehension of the transcendent Source of all those things. The former is a mathematical system involving intensive intellectual study, and the latter is a spiritual discipline involving the transcendence of the intellectual mind altogether. It's apparently only a very loose interpretation of physics, and a looser interpretation of mysticism, that allows for their surprising convergence—and opens the door to the even wilder idea that by drinking some of this quantum mystical brew, you'll be able to create your own reality.

Ken Wilber rejects quantum mysticism as it is usually currently formulated, humorously calling it the 415 syndrome (the area code of San Francisco), because the quantum mystical idea that quantum physics asserts that you can “create your own reality” seems to be common among New Age people who live in the San Francisco Bay Area.

Parodies

In 1998 Deepak Chopra was awarded the parody Ig Nobel Prize in physics for "his unique interpretation of quantum physics as it applies to life, liberty, and the pursuit of economic happiness.". He received this 'honour' for such writing as:

Quantum healing is healing the bodymind from a quantum level. That means from a level which is not manifest at a sensory level. Our bodies ultimately are fields of information, intelligence and energy. Quantum healing involves a shift in the fields of energy information, so as to bring about a correction in an idea that has gone wrong. So quantum healing involves healing one mode of consciousness, mind, to bring about changes in another mode of consciousness, body.
— Deepak Chopra

"Quantum philosophy"

In addition to mystical adaptations of quantum theory, postmodern/poststructuralist thinkers have been criticised for pseudoscientific references to quantum mechanics. An example was in the Sokal Affair of 1996, where Alan Sokal published a tongue-in-cheek paper entitled Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity (which refers to quantum gravity, an extension of quantum theory) in the postmodernist journal Social Text. The editors' acceptance of the nonsensical article earned them the 1996 parody Ig Nobel Prize. Sokal, with Jean Bricmont, went on to make a serious critique of the use of science by postmodern thinkers in their book Fashionable Nonsense.
