I'm sure you understand this but you realize how silly you sound so know message board pride has kicked in and you will continue to push your silly statements.
You said this:
A bit is a human construct! They don't "exist", they are purely conceptual. Just what exactly do you think a bit is? Do you really think that bits are actual physical components that are soldered into your computer? Show me a photograph of a bit And just how exactly do you think a computer works? You clearly haven't got a clue what you're talking about.
You then said:
Jeez, how are you failing to grasp this concept? A quantum computer and a qbit are human concepts and constructs, quantum computers don't exist in nature any more than the RAM or CPU in my computer does. None of this has anything at all to do with entanglement.
Saying qubits and bits are human constructs is just like saying x-rays or microwaves are human constructs. I have to believe you just have dug yourself into a hole that pride will not let you escape from. What you're saying is just silly.
A qubit occurs because of entanglement and superposition. These things occur in nature. A quantum computer will just harness the computing power that occurs on a quantum mechanical level. A quantum computer doesn't create entanglement or superposition no more than a radio creates radio waves or a microwave oven creates microwaves. Again, if you don't understand superposition and entanglement and how quantum computers work, then do some reading about it. It's really not that hard. Who created superposition if it's a human construct? Who created entanglement if it's a human construct? Who created qubits if it's a human construct?
In the race to build quantum computers, researchers are taking a number of approaches to creating qubits. Regardless of the approach, a common problem is making certain that information encoded into qubits isn't lost over time due to quantum fluctuations. This is known as "fault tolerance."

A computer works based on electrical signals. A high voltage signal is a 1 and a low voltage signal is an 0. We can store data like the color blue or the alphabet on these bits. The same thing occurs in nature unless you think electrical impulses don't happen in nature and electricity is a human construct.
Nature stores data on things like atoms and molecules.
It stores data like how a star goes supernova or how a comet forms or DNA.
This is why everything in the universe is information
and can be broken down to 1's and 0's.
They can even store bits on quantum space around a single electron with things like quantum holography.
I'm shocked in this day and age that you don't know this. This is just basic knowledge of the universe.

How are you struggling with this very basic concept? Seriously, even a child would have grasped it by now. X-rays exist in nature, correct. Have you ever seen a microwave oven, complete with rotating platter and digital timing interface roaming around in the wild? Of course not! You seem completely unable to grasp the difference between the physical construction of something and it's conceptual usage, as defined by man. Your line of thinking is as absurd as this: "Tables are made from wood, wood exists in nature, therefore tables harness the natural tableness of nature". How many times must I point this out to you?
Quantum computers don't even exist yet! And before you get your knickers in a twist, the DWave machine and it's workings has not actually been demonstrated to the scientific community and as such their claims are met with scepticism.
In 2009, researchers at Yale University created the first rudimentary solid-state quantum processor. The two-qubit superconducting chip was able to run elementary algorithms. Each of the two artificial atoms (or qubits) were made up of a billion aluminum atoms but they acted like a single one that could occupy two different energy states.[35][36]
Another team, working at the University of Bristol, also created a silicon-based quantum computing chip, based on quantum optics. The team was able to run Shor's algorithm on the chip.[37] Further developments were made in 2010.[38] Springer publishes a journal ("Quantum Information Processing") devoted to the subject.[39]
A team of scientists from Australia and Japan have finally made a breakthrough in quantum teleportation. They have successfully transferred a complex set of quantum data with full transmission integrity achieved. Also the qubits being destroyed in one place but instantaneously resurrected in another, without affecting their superpositions.[40]
So when will there be a real quantum computer?
It depends on your definition. There are quantum computers already, but not of sufficient power to replace classical computers. A team of researchers from IQC and MIT hold the current world record for the most number of qubits used in an experiment (12). While practical quantum technologies are already emerging — including highly effective sensors, actuators and other devices — a true quantum computer that outperforms a classical computer is still years away. Theorists are continually figuring out better ways to overcome decoherence, while experimentalists are gaining more and more control over the quantum world through various technologies and instruments. The pioneering work being done today is paving the way for the coming quantum era.
So quantum technology is still years away?
No, quantum technologies are already in use! Quantum Key Distribution is already commercially available, and will greatly benefit from new research (scientists at IQC are currently pursuing quantum encryption through free space via satellite). Although a fully functioning quantum computer is a longer-term goal, many fundamental and practical discoveries have been made in the name of quantum computing. Quantum sensors and actuators will allow scientists to navigate the nano-scale world with remarkable precision and sensitivity. Such tools will be invaluable to the development of true quantum information processors. The quantum revolution is already under way, and the possibilities that lie ahead are limitless.

You don't understand information.
Nobody ever said nature can produce a microwave. I said humans can build a technology that gives us a microwave oven. We can take Data or information in a high state of entropy and arrange that data into a low state of entropy to convey a message.So both the microwaves and the microwave oven are constructs of information.
It takes energy to turn information in a high state of entropy into information in a low state of entropy. This is why information and entropy are linked.
Again, bits and qubits are not human constructs. Who invented the qubit? Who invented superposition? Who invented entanglement?
You claimed that the qubit was a human construct. Back up your claim. Who invented the qubit?
The concept of the qubit was unknowingly introduced by Stephen Wiesner in 1983, in his proposal for unforgeable quantum money, which he had tried to publish for over a decade.

Wrong again.

Recently, diamond-based qubits created a flurry of interest because their "decoherence" time (the time that they can retain their logic state) is much longer than the time it takes to perform a logical operation – even at room temperature. What is more, they can be read-out using light, which means that they could potentially be integrated into photonic quantum-information-processing systems. However, making these qubits remains a challenge – both in terms of cost and scaling-up the technology to make multi-qubit integrated circuits.

A quantum computer, on the other hand, uses quantum bits, or qubits. What's the difference? Well a qubit is a quantum system that encodes the zero and the one into two distinguishable quantum states.
More off-topic rambling
Big deal! That doesn't in anyway invalidate what i said. I noticed you skipped the point I hammered home so I'll have to repeat it again in the vain hope you might grasp it: researchers are taking a number of approaches to creating qubits.
Quantum computers don't even exist yet!
The qubit is described by a quantum state in a two-state quantum-mechanical system, which is formally equivalent to a two-dimensional vector space over the complex numbers. One example of a two-state quantum system is the polarization of a single photon: here the two states are vertical polarization and horizontal polarization. In a classical system, a bit would have to be in one state or the other, but quantum mechanics allows the qubit to be in a superposition of both states at the same time, a property which is fundamental to quantum computing.
See? Qubits are a human construct used to encode Boolean states (another human construct).

LOL, yeah it's a big deal because quantum computers exist. You said:

You were so sure of this you put an exclamation mark behind it.
WRONG!!! There's 3 exclamation marks for you.
Qubits are not a human construct. When you build a microwave oven you don't have to create microwaves. When researchers say they're creating qubits, they're putting electrons or photons in a state of superposition which already occurs in nature.
They're not making qubits anymore than a person who makes a radio makes radio waves. You can create qubits if you put an electron in a state of superposition. Nobody is creating superposition or entanglement. Nobody invented or created a qubit. It exist because of superposition.

Superposition produces the Qubit not the people in the lab. It would be like saying if the people at the LHC find the Higgs Boson they would have created the Higgs Boson. They just built a machine that can recreate conditions that occur in nature.
Just like a quantum computer will create conditions that already occur in nature which is superposition. When an electron is in superposition it's already in a binary state. Instead of being a 1 or an 0 like a classical bit it's a 1 and 0 at the same time because of superposition. So we just have to create a machine(quantum computer) that will allow superposition to stay in place as we scale up instead of becoming entangled because of decoherence.
When a particle is in superposition it's a qubit. It's the probability amplitude of the superposition that creates qubits.
You said:

Nope, qubits are a construct of superposition.
Do you know anything about superposition and probability amplitudes? It's just like a high voltage 1 or a low voltage 0 in a classical computer, except in a quantum computer the high voltage 1 or low voltage 0 is replaced by superposition and probability amplitudes. For instance horizontal polarization could be a 1 and vertical polarization can be an 0. If you can build a machine that holds this superposition then you can have a powerful, scaled up quantum computer. We're just translating what already occurs on a quantum level to a classic level.
Name me one human concept that's not based on information. Humans just take information in a high entropy state and arrange it in a low entropy state to convey a message.
If the universe is not a construct of information name me one concept that isn't based on information?
I'm waiting for you to tell me who invented superposition and who invented the qubit.
You clearly do not understand the source material you are posting. One last time: a qbit means quantum bit. A bit is a man made concept used in representing another man made concept, the binary number system.
While physicists struggle to make the first practical quantum computer, nature is full of them. According to theoretical chemist Graham Fleming of the University of California at Berkeley and colleagues, photosynthesis achieves its formidable efficiency by conducting a quantum-computing search algorithm. This process finds the best route for shifting energy from light-absorbing molecules to the photosynthetic reaction centre, where it is used to drive chemical reactions.
Previously, scientists assumed that the light energy - in the form of excited molecular electronic states called excitons - finds its way to the reaction centre via random hops between chromophores with successively lower energy levels, like a stream of water meandering downhill. But Fleming and colleagues now say that a broader view informs this path: the energy is smeared out over many electronic states in a quantum superposition, in effect being in many different states at once. In this way it 'samples' the routes available to it, and finds the path of least resistance. That may account for why this part of the photosynthetic process, in which light energy is converted into chemical energy, is so efficient: typically 95 percent or more of the absorbed energy is funnelled to the reaction centre.
Yes the FACTS to change.
There's a huge difference between the universe being a material objective reality or a construct of information.
The reason we have all of these paradoxes in science and there's a gulf between quantum mechanics and classical physics is because some scientist treat the universe as an objective material reality.
Many of these paradoxes and problems go away when you look at the universe as a construct of information.
Again, you're making a philosophical argument and this is a debate about science.
Of course it makes no difference in the context of philosophy.
If you think and experience it as real then it's reality to you.
In the context of science there's a huge difference if the universe is an objective material reality or a construct of information.
There are no truly simultaneous events. Relativity is valid in all levels.
The machine is physical.

Basic steps towards the creation of a quantum computer have been taken, with the demonstrations of elementary data storage and manipulation using photons and atoms or trapped ions as the quantum bits, or "qubits". Recently, it has been shown that it is possible to build solid-state qubits made from tiny samples of superconducting material. Figure 01 shows some of the subjects, which are currently being investigated in the field of quantum computing.
Designing a qubit is especially difficult. If they are made from single rubidium atoms, for example, they are less susceptible to the influence of stray magnetic fields that can ruin their ability to be in the “on and off” state.
In their innovation, the NIST team created a qubit made of two atoms, in which one was the “memory” and the other the instrument for “processing.”
Photons are good candidates for qubits because they can easily be prepared in a superposition of two (polarization) states, but how might a memory device for such qubits be made without effectively making a measurement on them and destroying the quantum information?
The main characteristics of good qubits are long coherence times in combination with fast operating times. It is well known that carbon-based materials could increase the coherence times of spin qubits, which are among the most developed solid-state qubits. Here, we propose how to form spin qubits in graphene quantum dots.
The most remarkable new feature of the proposed spin qubits is that, in an array of many qubits, it is possible to couple any two of them via Heisenberg exchange with the others being decoupled by detuning.
“There are several ways to make qubits with light,” Pfister explains. “One is to use a resonant mode of a cavity. A single laser cavity has millions of harmonic modes, and if you can design it, your scalability problem is solved.”
“There are a lot of tools available right now to make qubits, and this is one of them,” Pfister continues. “Our experiment shows a great potential for scaling up the number of entangled qubits that can be used in quantum processing. We are another step closer.”
“The color centers in diamond are very interesting as qubits for quantum information processing, where they can be used as memory to store information,” says Lončar. “More importantly, they can be interrogated—they can be written into and read out—with light.”
But no existing quantum computing architecture—that is, how we make quantum bits (qubits) and perform operations on them—is really all that satisfying. If you don't even know which materials are best for building a quantum computer, it makes progress awfully slow.
As a result, a lot of researchers have moved away from constructing proof-of-principle demonstrations of quantum computing, and are now trying to create clever ways to make qubits better behaved. A pair of papers look into the prospects for using impure diamonds as an architecture for quantum computing
How do you make a qubit from impure diamond? The electrons in carbon are arranged so that four of its electrons wish they had the company of four other electrons—hence, in diamond, each carbon atom has four carbon atom friends. If we add a nitrogen atom into the mix—making the diamond yellow in color—then there is a problem.

• coherence/decoherence
• qubit readouts and measurements
• coupled qubits
• conclusion
Just like a normal computer bit, a qubit can adopt the states ‘0’ and ‘1’. One way to make a qubit is to trap a single electron in semiconductor material. It’s state can be set by using the spin of an electron, which is generated by spinning the electron on its axis. As it can spin in two directions, one direction represents the ‘0’ state, while the opposite direction represents the ‘1’ state.
