Quantum Machine Learning is defined as the branch of science and technology that is concerned with the application of quantum mechanical phenomena such as superposition, entanglement and tunneling for designing software and hardware to provide machines the ability to learn insights and patterns from data and the environment, and the ability to adapt automatically to changing situations with high precision, accuracy and speed.

Quantum fluctuations are, at their root, completely a-causal, in the sense that cause and effect and ordering of events in time is not a part of how these fluctuations work. Because of this, there seem not to be any correlations built into these kinds of fluctuations because 'law' as we understand the term requires some kind of cause-and-effect structure to pre-exist. Quantum fluctuations can precede physical law, but it seems that the converse is not true. So in the big bang, the establishment of 'law' came after the event itself, but of course even the concept of time and causality may not have been quite the same back then as they are now.

Quantum Mechanics can indeed be extremely complex to grasp, but when we talk about Consciousness, with decades of rigorous studies on the human brain we have realized that actually, there is no other phenomenon in the entire universe that is simpler than the majestic phenomenon of Consciousness. 'If you think you have a solution to the problem of consciousness, you haven’t understood the problem.' This age-old metaphysical and philosophical argument is strictly not true. If you are sufficiently clear-sighted enough, you can realize the problem itself was a matter of the past when we didn’t have insight into the neurological basis of consciousness. And today it is common knowledge in Neuroscience that, all mesmerizing features of the Human Mind, including the glorious Human Consciousness, are born from the tiny specks of jelly inside your head.

Quantum physics tells us that no matter how thorough our observation of the present, the (unobserved) past, like the future, is indefinite and exists only as a spectrum of possibilities. The universe, according to quantum physics, has no single past, or history. The fact that the past takes no definite form means that observations you make on a system in the present affect its past.

Quantum mechanics. What a repository, a dump, of human aspiration it was, the borderland where mathematical rigor defeated common sense, and reason and fantasy irrationally merged. Here the mystically inclined could find whatever they required and claim science as their proof. And for these ingenious men in their spare time, what ghostly and beautiful music it must be--spectral asymmetry, resonances, entanglement, quantum harmonic oscillators--beguiling ancient airs, the harmony of the spheres that might transmute a lead wall into gold and bring into being the engine that ran on virtually nothing, on virtual particles, that emitted no harm and would power the human enterprise as well as save it. Beard was stirred by the yearnings of these lonely men. And why should he think they were lonely? It was not, or not only, condescension that made him think them so. They did not know enough, but they knew too much to have anyone to talk to. What mate waiting down the pub or in the British Legion, what hard-pressed wife with job and kids and housework, was going to follow them down these warped funnels in the space-time continuum, into the wormhole, the shortcut to a single, final answer to the global problem of energy?

So much love, so much time.

Seriousness of mind was a prerequisite for understanding Newtonian physics. I am not convinced it is not a handicap in understanding quantum theory.

She figured that the main problem in physics is physicists, that most of them are caught in a mind trap because they're so used to things being made of smaller things. So they instinctively believe that reality, at its most basic level, must be made up of and regulated by almost infinitely small elementary particles.

The answer to the ancient question 'Why is there something rather than nothing?' would then be that ‘nothing’ is unstable.

The Copenhagen Interpretation has long been the orthodox view of the quantum world and this is not surprising considering how weird the alternatives are. However realism has usually been assumed in the macro world, but given the modern research into animal senses, neurology, and cognitive psychology, realism must inevitably cease to be a serious explanation of the macro world. It seems quite obvious the macro world is sense dependent and the orthodox interpretation of the quantum world postulates a sense dependent world as well. This suggests the same rules can apply to both the macro and quantum worlds which eliminates the need for a dividing line between the two worlds.

The belief in causality is metaphysical. It is nothing but a typical metaphysical hypostatization of a well-justified methodological rule- the scientist's decision never to abandon his search for laws. The metaphysical belief in causality seems thus more fertile in its various manifestations than any indeterminist physics metaphysics of the kind advocated by Heisenberg. Indeed, we can see that Heisenberg's comments have had a crippling effect on research. Connections which are not far to seek may easily be overlooked if its continually repeated that the search for any such connections is 'meaningless'.

The mind reels when we realize that, according to this interpretation of quantum mechanics, all possible worlds coexist with us. Although wormholes might be necessary to reach such alternate worlds, these quantum realities exist in the very same room that we live in. They coexist with us wherever we go.

The nature of the 'collapse of the wave function' is determined by our self-concept stored in the subconscious mind. Our subconscious mind is aware of the 'many-worlds' occurring simultaneously and chooses the reality we continue to exist in based on our self-concept.

The particles that are the very building blocks of all things, are in all possible locations until observation/measurement causes them to choose a specific position.

The Quantum Mechanic will fix your car, but it won’t work unless you observe him fixing it

The more we delve into quantum mechanics the stranger the world becomes; appreciating this strangeness of the world, whilst still operating in that which you now consider reality, will be the foundation for shifting the current trajectory of your life from ordinary to extraordinary.

The [quantum] theory reminds me a little of the system of delusions of an exceedingly intelligent paranoiac.

There are many, many, many worlds branching out at each moment you become aware of your environment and then make a choice.

Some people, including Hawking, think that we may be able to understand the big bang or the big crunch (in particular, whether time has a beginning or an end at these events) when we have a satisfactory quantum theory of gravitation.

There’s a cellular automaton called TVC. After Turing, von Neumann and Chiang. Chiang’s version was N-dimensional. That leaves plenty of room for data within easy reach. In two dimensions, the original von Neumann machine had to reach further and further - and wait longer and longer - for each successive bit of data. In a six-dimensional TVC automaton, you can have a three-dimensional grid of computers, which keeps on growing indefinitely - each with its own three-dimensional memory, which can also grow without bound. And when the simulated TVC universe being run on the physical computer is suddenly shut down, the best explanation for what I’ve witnessed will be a continuation of that universe - an extension made out of dust. Maria could almost see it: a vast lattice of computers, a seed of order in a sea of random noise, extending itself from moment to moment by sheer force of internal logic, “accreting” the necessary building blocks from the chaos of non-space-time by the very act of defining space and time.

There are just some things that are outside of comprehension, even if we can quantify them. At some point, science becomes magic.

The strength of the familiar electromagnetic force between two electrons, for example, is expressed in physics in terms of a constant known as the fine structure constant. The value of this constant, almost exactly 1/137, has puzzled many generations of physicists. A joke made about the famous English physicist Paul Dirac (1902-1984), one of the founders of quantum mechanics, says that upon arrival to heaven he was allowed to ask God one question. His question was: "Why 1/137?

The subconscious mind is the guiding force for your entire life.

The subconscious mind is aware of the many worlds unfolding in each moment.

The subconscious mind is shielding or showing numerous potential paths, based on what it determines would represent a consistent reality for you.

The TVC universe will never collapse. Never. A hundred billion years, a hundred trillion; it makes no difference, it will always be expanding. Entropy is not a problem. Actually, ‘expanding’ is the wrong word; the TVC universe grows like a crystal, it doesn’t stretch like a balloon. Think about it. Stretching ordinary space increases entropy; everything becomes more spread out, more disordered. Building more of a TVC cellular automaton just gives you more room for data, more computing power, more order. Ordinary matter would eventually decay, but these computers aren’t made out of matter. There’s nothing in the cellular automaton’s rules to prevent them from lasting forever. Durham’s universe - being made of the same “dust” as the real one, merely rearranged itself. The rearrangement was in time as well as space; Durham’s universe could take a point of space-time from just before the Big Crunch, and follow it with another from ten million years BC. And even if there was only a limited amount of “dust” to work with, there was no reason why it couldn’t be reused in different combinations, again and again. The fate of the TVC automaton would only have to make internal sense - and the thing would have no reason, ever, to come to an end.

The very small quantum world, it seems, is a mixture of possibilities. The quantum fields to which all particles belong are the sum of these possibilities and, somehow, one possibility is chosen out of all the existing ones just by seeing it, just by the very act of detecting it, whenever one tries to probe a particle's nature. Nobody knows why or how this happens.

There has been much controversy about what is meant by an observation causing a quantum entity to come into existence. The controversy is caused by ambiguity in the meaning of terms such as existence and reality. No one seems to know what they mean in the context of quantum mechanics, so I will explain what they mean. The correct interpretation is that when we say that quantum entities do not exist except when observed, we mean they do not exist as part of the human sensory world created by the human sensory apparatus, when an observation is made. The human sensory world is the world we know and live in, and is the world given to us by our sensory apparatus. There is nothing to stop quantum entities existing in other worlds when being observed in the human sensory world and when not being observed in the human sensory world. In addition all observations made by a human observer are personal to that observer, although other human observers will perceive something very similar to that which is observed by other human observers due to having very similar sensory apparatus. The evidence we perceive in our experiments which indicates the presence of quantum entities should be treated in the same way as our perceptions of tables, trees and people in the macro world. ... We don't actually see quantum entities, we see macro level evidence the quantum entities exist, and this macro level evidence comes into existence in exactly the same way as everything else in the macro world. The solution to the quantum measurement problem lies not in the quantum world, but in how the human sensory apparatus works in the macro world.

To access your subconscious, is to access your 'higher-self.

To apply quantum theory to the entire universe... is tricky... particles of matter fired at a screen with two slits in it... exhibit interference patterns just as water waves do. Feynman showed that this arises because a particle does not have a unique history. That is, as it moves from its starting point A to some endpoint B, it doesn’t take one definite path, but rather simultaneously takes every possible path connecting the two points. From this point of view, interference is no surprise because, for instance, the particle can travel through both slits at the same time and interfere with itself. In this view, the universe appeared spontaneously, starting off in every possible way.

To strengthen the connection between your conscious and subconscious, is to gain access to a map and compass, as you travel through parallel worlds.

To shift your life in a desired direction, you must powerfully shift your subconscious.

Universe is like a soup of consciousness. Brain is just a receiver. Awareness is continuously transforming thoughts into matter.

We are a manifestation that we perpetuate through space-time. Death is the ceasing of the observation of it whether by direct or indirect influence.

We are Love experiencing itself, in myriad ways.

We are not talking about waves or particles, what we are talking about is a quantum of action in a field. This thing we call a particle is a quantum of action that becomes more focused by a process we have not described and this thing we call a wave is the potential in the field. How can a wave be quantized? The wave is a precise ratio of potential.

We’re really just unwitting pawns playing out a sinister predetermined plan laid out by the toaster.

What causes the collapse of the wave function? It is the entry of stimuli into the sensory apparatus of a conscious observer, such as photons of the right wave length hitting the human eye and entering the eye through a lens which focuses the light on to the retina. The retina then sends a signal to the brain via the optic nerve and the brain turns the information into the images we see. Those images and information from the other senses constitute the human sensory world. Clearly the images and other information could not exist without observation. Nothing else in the human sensory world exists without an observation being made, so why should the results of experiments, indicating the presence of quantum entities, which show in macro level experimental apparatus be any different?

To study the self is to forget the self. Maybe if you sat enough zazen, your sense of being a solid, singular self would dissolve and you could forget about it. What a relief. You could just hang out happily as part of an open-ended quantum array.

[..] when we get down to the subatomic level, the solid world we live in also consists, again rather worryingly, of almost nothing and that whenever we do find something it turns out not to actually something, but only the probability that there may something there.

When you ask what are electrons and protons I ought to answer that this question is not a profitable one to ask and does not really have a meaning. The important thing about electrons and protons is not what they are but how they behave, how they move. I can describe the situation by comparing it to the game of chess. In chess, we have various chessmen, kings, knights, pawns and so on. If you ask what chessman is, the answer would be that it is a piece of wood, or a piece of ivory, or perhaps just a sign written on paper, or anything whatever. It does not matter. Each chessman has a characteristic way of moving and this is all that matters about it. The whole game os chess follows from this way of moving the various chessmen.

When you look at the external reality, you may assume you know everything, but when you close your eyes and try to look into the darkness of your internal reality, all the knowledge of the external life fails to create a way out of the darkness.

Where misunderstanding dwells, misuse will not be far behind. No theory in the history of science has been more misused and abused by cranks and charlatans—and misunderstood by people struggling in good faith with difficult ideas—than quantum mechanics.

Yet, at the quantum level, NO part of the body lives apart from the rest. There are no wires holding together the molecules of your arteries, just as there are no visible connections binding together the stars in a galaxy. Yet arteries and galaxies are both securely held together, in a seamless, perfect design. The invisible bonds that you cannot examine under a microscope are quantum in nature; without this "hidden physiology," your visible physiology could not exist. It would never have been more than a random collection of molecules.

You are deluded if you think that the world around you is a physical construct separate from your own mind.

You are the individual and the entire Universe.

There was a young lady named Bright, Whose speed was far faster than light; She started one day In a relative way, And returned on the previous night.

All perception is the result of electrical impulses in the brain - the world of the individual is tantamount to a highly advanced computer running and analyzing programs in its working memory.

Quantum mechanics makes absolutely no sense.
