The technology era has used small pieces of quantum mechanics [QM] for many years. We just were not aware of QM.  Scientists referred to all this as classical science and we referred to it as radios, TV, microwaves, refrigerators, videos and computers, We used the early simple everyday explanation of how things worked as we saw them, until scientists realized that matter and things were made up of very small particles like atoms and nuclei, that had electrical energy, referred to as electrical molecules and atoms as packits or quantas or quantum; basically quantum mechanics [QM].

So what is quantum to begin with? Quantum is the smallest matter that can be used to describe a physical happening. We see a person as a big whole object; this is referred to as classical science. However, Quantum recognizes the human body as invisible vibrating waves of atoms, electrons and nuclei.

Quantum mechanics is the study of matter and its interactions with energy on the scale of atomic and subatomic particles. By contrast, classical physics explains matter and energy only on a scale familiar to human experience, including the behavior of astronomical bodies such as the moon. Classical physics is still used in much of modern science and technology. However, toward the end of the 19th century, scientists discovered phenomena in both the large (macro) and the small (micro) worlds that classical physics could not explain. The desire to resolve inconsistencies between observed phenomena and classical theory led to two major revolutions in physics that created a shift in the original scientific paradigm: the theory of relativity and the development of quantum mechanics.  Wiki: Quantum physics

Let's explore the properties of quantum mechanics.

The rules of quantum mechanics differ from that of classical science in two very weird, almost magical ways.

Quantum superposition: First, in classical science, objects are in one place at one time. You are either at the store or at home, but not both. But in quantum mechanics, subatomic particles can theoretically exist in multiple places at once before they’re observed. A single subatomic particle can exist in point A and point B at the same time until we observe it. And at that point, it only exists at either point A or point B. So, the true “location” of a subatomic particle is some combination of all its possible positions. This is called quantum superposition.

Quantum entanglement is the second part of quantum mechanics. In classical mechanics; objects can only “work” with things that are also “real.” You can’t use an imaginary friend to help move the couch. You need a real friend instead. But in quantum mechanics, all those probabilistic states of subatomic particles are not independent. They’re entangled. That is, if we know something about the probabilistic positioning of one subatomic particle, then we know something about the probabilistic positioning of another. That means these already super-complex particles can actually work together to create a super-complex ecosystem. This is called quantum entanglement. So, in short, subatomic particles can theoretically have multiple probabilistic states at once. And all those probabilistic states can work together — again, all at once — to accomplish some task.

However today, Quantum technology is set to revolutionize the way we think about health care, medical data, and even our own biology.

Gregg Henriques, Professor at James Mason University, wrote in Psychology Today, that: "All of our deeply embedded physiological and metabolic traits have evolved in compliance with Quantum Mechanics [QM] from the beginning of life. Most of these cannot be measured as aspects of our primary senses, but nevertheless, biology channels a large variety of quantum phenomena into a wide range of environmental cues that affect our cells. The common denominator is that all of these quantum effects are directed toward the maintenance of essential cellular homeostasis. Therefore, the influences of QM are profound and extend into every aspect of our biological selves. .... The entire physiology of the cell has evolved from QM principles from the first primitive cells forward. That path is unbroken since cellular life began. The first cells adapted to earth’s environment based on a set of First Principles of Physiology."  Henriques: Quantum & You 2019

Indeed, the human body is a collection of numerous complex pieces of quantum that date back millions of evolutionary years. Mother nature used quantum mechanics to simplify how the body works and how we live. Mark Anstendig, referred to the whole human body as: "a biological-chemical-electrical precise, delicate and complex machine that works in hidden and mysterious ways. The human body is a big machine consisting of many different smaller interconnected machines. Each machine (heart, lungs, brain, intestines, eyes, etc.) runs at its own individual speed, but all function in a specific, predetermined relationship to each other. In this sense, the body is analogous to the most complicated man-made machines, such as automobiles, tape recorders, or space capsules, which consist of many separately functioning components that are mechanically linked together, each of which, in itself, is a complete machine. All aspects of the body work seamlessly as an integrated functional package. The whole body can adapt in mysterious ways." Anstendig: Body is a machine 1982 The human body is a complex quantum machine.

There is speculation by William Busell and Maureen Seaberg that humans can observe quantum phenomenon.  Seaberg: Human observe quantum 2019

We can learn from plant photosynthesis how the body works. Classical science tells us that chlorophyll captures the sunshine through photosynthesis to make plant sugar. But the process is much more complicated than this. Chlorophyll works in photosynthesis by synchronizing thousands of cells to form liquid crystal structure that acts as a biological superconductor of the sun's energy. This phenomenon is called resonant energy transfer and can only happen when all those molecules are in a state of quantum coherence.  Selbie: Quantum & human bodies:

In a 1998 study, geneticist and quantum biologist Mae-Wan Ho and her team were amazed to find liquid crystalline domains virtually everywhere in living tissues. The relevance of liquid crystal in all living things is that most tissues in the human body exist indefinitely in quantum coherent states.  Selbie: Quantum & human bodies:  Ho: Organism & psychic in universe 1999 Ho and her researchers found that:

Our living body is an incredibly colorful, liquid crystalline continuum, with all parts rapidly intercommunicating and colors flashing, so that it can act as a coherent whole.

One has been led to believe that intercommunication in large animals like ourselves depends on the nervous system controlled by the brain. However, that may be only half the story, as nerves do not reach all parts of the body, and animals without a nervous system nevertheless have no problems in acting as a coherent whole. The clue to the other half of the story is in the connective tissues which make up the bulk of most animals including ourselves. These are the skin, the bones, cartilage, tendons, ligaments and other tissues that fill up the spaces between the usual organs. Most people still think that these tissues fulfill mechanical functions of protection and support, like packing material. However, we now know they are all liquid crystalline, and have much more exotic properties.

Ho's explanation of how liquid crystals connect with all body parts also explains how the body coordinates communication beyond nerves in an instant manner.

A yet more interesting possibility is that the liquid crystalline continuum may function as a quantum holographic medium, recording the interference patterns arising from interactions between local activities and a globally coherent field.

The conditions are there for a quantum holographic memory store in the liquid crystalline continuum of the body itself. Holographic memory is unique in that it is distributed globally, and yet, can be accessed and recovered locally. It captures an aspect of the organic whole in developmental biology that has completely eluded mechanistic understanding.

Quantum opens the door to better understand life, that is, how people interact with each other in a community. When many individuals in a society have a certain rapport with one another, they may constitute a coherent whole, and ideas and feelings can indeed spread like wildfire within that community. In the same way, an ecological community, and by extension, the global ecology may also be envisaged as a super-organism within which coherence can be established in ecological relationships over global, geological space-times.

Ofcourse these quantum possibilities are merely scratching the top of the iceberg for information. There is a lot more to learn from quantum.

Another everyday mystery is how our brain works. Classical science explains how the brain works like a computer. It is the brain-mind that helps us to think. But it is during sleep that the brain sorts out the day's memories and stores these as holograms. In a quantum state the brain helps to solve personal and world problems. More about this brain mystery in:  Fascination

Another example of the difference between classical science and quantum mechanics is how the computer works in each case.

Today’s computers are built on top of the laws of classical mechanics. That is, they store information on what are called bits, which can store data narily as either “1” or “0.” But what if you could turn those classical bits into quantum bits – qubits – to leverage super positioning to be both “1” and “0” stores at once?

Currently, to search through its catalogue of data, a computer must go through a list of ‘markers’ that describe every item. Looking for a “hot dog”? Maybe the markers for that item are “Food”, “Edible”, “Carbohydrate”, etc. Each marker, at a minimum, requires bits of information that distinguish one marker from other ones, and bits that note whether or not said marker is applicable or not." For a quantum computer, there might not have to be separate bits that denote whether a marker is applicable or not, because a qubit can represent that data inherently. This means that a single qubit of data is able to express what once required an entire cluster of bits. Quantum computing will allow the calculation of much more information at a much faster rate.

Quantum computing changes the game of understanding matter and things in its entirety. Rather than computing using ‘bits’, quantum computing utilizes ‘qubits’ (quantum bits). The biggest difference is that qubits can combine more states of information rather than just the two of bits.

It is the expectation that Super fast Quantum computers in the future will bring about many medical advancements that will improve health of patients:  Smith: Quantum medicine 2021

• Faster genetic analysis could lead to more efficient screening for genetic diseases and help design personalized medicine based on an individual's genetic composition.
• Researchers at the University of York have designed a patch that replaces a single syringe with many little polymer nanofilaments that deliver medication through hair follicles.
• new approach is sensitive and stable enough to be used as imaging diagnostics
• possibility of 10 000-times faster drug candidate testing
• make healthcare quicker and less painful.
• Make way for more personalized medicine
• improved disease screening and treatment
• better understanding of how the human body works

Scientists hope to utilize unusual quantum properties to develop medical tools, diagnostics, and treatments that are incredibly precise and ultra-personalized, tools that will ultimately improve and lengthen lives. Using quantum mechanics in medicine and analyzing properties in food could provide disease detection in the early stages or highlight risks of disease before they manifest themselves.

Smith perceives: "Quantum physics has the potential to revolutionize many aspects of everyday life, medicine and healthcare. The laws of quantum physics define the human body as a quantum system, from the smallest vibrations and energy units that communicate with each other. Quantum physics could be the key to solving the current issues in healthcare and bring in a new era of integrative medicines: utilizing the complex rules of quantum mechanics. Scientists aim to make medicine faster, less painful, and more personalized."  Smith: Quantum medicine 2021

The hype created by hopefuls that quantum theory is the answer to better medicine and health of everyone is speculation. 

The future of applying quantum mechanics to everyday life is still probably 10 or more years away. Classical science explains how medicine works for doctors, but QM can help the general population understand how their body works. Classical science tries to explain the impact vitamins, minerals and proteins have on the body. But QM can simplify the complexity of food, exosomes, phytochemicals, our understanding of how food is used by the body to enhance health, prevent diseases, clarify human needs and extend longevity.

So the hidden unspoken mystery of quantum computers is that quantum computers require extremely low temperatures to operate: about -460F, or near absolute zero. Wall: QM computing needs ice cold 2017   Will WM computers work at room temperature? We have difficulty unraveling the need for absolute zero quantum temperature with that of the of ambient air and the human body body 96.7 F. There is a lot we do not know!

But before QM can help the general population improve their wellbeing, the big leap in technology needs to be be quantum computing. Numerous countries around the world are trying to build quantum computers. The chart below identifies companies in United States building quantum computers that will be about 158 million times faster than the world’s fastest supercomputer today:

Today we have stumbled, not fully understanding quantum, using a few properties of quantum mechanics to build TVs, the internet, robots, artificial intelligence [AI], cell phones, electric batteries and electronic cars [EV]. With the help of quantum computing, we could be 5 to 10 years away from $15,000 EVs that can drive up to 1,000 miles or more on a hopeful quantum single battery charge. We are at the beginning of quantum evolution.
