What Is Quantum Computing?

The technological landscape is ever changing and it is a very difficult task to predict how it will be evolving in the coming years.

At the present many scientists are already convinced that quantum computers are the future. So what is this quantum computing? Let’s take a look.

A quantum computer is a device for computation that makes direct use of quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data…..The basic principle behind quantum computation is that quantum properties can be used to represent data and perform operations on these data.”

That’s according to an article on Wikipedia.

We know that some of you might have felt the above definition passing over your head like a speeding bullet.

To make things a bit simpler, a quantum computer uses the principles of quantum physics to make its computational power far greater than that of a traditional computer. Quantum computing makes computations on atoms themselves.

As you might know, the machine that you are staring onto at the moment stores data in a binary number format. A classical computer has bits which represent either a 1 or a 0.

In place of bits, a quantum computer has quantum bits (qubits) which can represent a 0, 1, or a superposition of both. While a quantum computer is capable of storing more than one number in a single register at a time, a traditional computer can store only a number. Quantum computers will also be capable of making calculations on a far greater order of magnitude than the machines that are available on the market nowadays.

At the present moment, Japan’s K computer, which is the world’s fastest supercomputer, has approximately the processing power of a human brain. If ever humans manage to master the technology of quantum computing, the computing power available as a result will be larger than life itself.In reality we are very far away from that, though.

Although many think that quantum computers will replace silicon chips in the coming years, there are many challenges ahead and many more will arise as studies advance.

So far, a handful of quantum computers have been built. The first one was a 2-qubit quantum computer which was built in 1998. After a couple of years, a 7-qubit quantum computer was achieved. Then later on, D-Wave, a Canadian company, built a 16-qubit quantum computer which was able to compute several complex patterns and identify matching systems.

Despite these early successes, we have a long way to go and a lot of challenges as well. One such challenge is managing the disturbance that exists in the world around a quantum computer. The tiniest disturbances can affect the quantum computing system, and the uncertainty that is a fact when it comes to the quantum level is yet another issue.

But if man succeeds in harnessing the power available at the quantum level, life definitely won’t be the same for all. Let’s wait and see what the future holds for quantum computing.

    i challenge you to research any of the terms i have used here. Nothing I have said here is factually innacurate. ….

    i think black holes are natures organic computer—the more entripic an enviroment the mroe information it can simulate.

    go to google and put in ‘the ultimate laptop: a black hole’ to get a gist of the idea. (more entropy= greater ability for simulation–complexity is the pattern getting less repetative, which paradoxically makes it simultaneously more ‘chaotic’ or ‘random’–entropic–which is why keygens on the internet use irrational numbers to crack codes, because they ‘contain’ the simpler patterns)

    reality is after all, information. Its based on a source code and that source code is the same one  ‘running’ us. So, if we were to ever become self aware of it, we would be self actualizing the universe and the seperation between the universe and us would break down–because by containing the same information or being s elf aware of it, we will act and functionally, information wise, be it–identical–once you know the optimum strategy of a game it makes nos sense to play it (tic tac toe), so once we gain sufficient knowledge for control of reality, we will not see it seperate anymore as our need to control it dissappears and we become one, as we will know the very source code or root of the reality.

    Since reality is based on rules, like any computer program, then, it makes sense we will be able to then ‘manipulate it’ like any programmer—since energy will become irrelevant as information and intelligence allows us the most efficient way to ‘loophole’ any manifested reality—we will after all know the exact root code (think of the environemnt ,the more we have grown in knowledge with respect to biology ,the more we can control it, same with any other science, it only makes sens that once we know the root rule construct, we will then just enhance our intelligence and seslf awareness of it until any loophole every manifestation point for a possible reality we might want to acccess we will know, all it will take is will, and it shall be).

    Dont want to be too blasphemous with the notion of God, but my personal opinion is that this has already happened–i nfact, God exists in my mind and is running on the plank scale of the universe—the wave function of the universe or ominverse (whichever it is), because as a more entropic enviroment, it will also simulate the most information–meaning any ‘singularity’ will inevitably simulate and run information on the universe itself, the universe essentially being information.

    The only reason I put this down is for thought–it doesnt really have anything to do with our current development in computerization, although thats where I think it will inevitably lead. Furthermore, since it has already happened (even though its in the future–because the wave function of the universe is time independent)–I think  we can access it right now. I dont know how we can do this as humans but I do think it is possible. Some have suggested to me that many ancient eastern traditions such as taoism showed methods of meditation that perhaps are allowing the mind to access this boundless existence at the plank scale. Others that the frequency of love ‘makes our information lighter and hence more accessible–more information rich” It may also be that people who die, get ‘glued’ onto this higher dimensional construct, since humans are essentaily information systems (our cells change every 6 months)—but of course, this is all speculation. I am not one to beleive in empiricism but a priori tautology as a form of knowledge—because fundamentally we define or end up picking out data from the enviroment that matches our own semantic complexity–the mind itself collapses the wave function of reallity and so the observed and observer are intertwined, an inseperable manifold, not seperate entities. In my thought process, it makes sense to assume these things but as a general discussion on technology and computation it is irrelevant .You might find these thoughts interesting however, thats why i posted them.

    put in ‘the omega point simulation’ in youtube and look johananratz’s video, should give you an idea of what im thinking. Also, I dont ascribe to the general concept of the omega point as described by tipler (like with computers–im talking about using the universe itself as a computer), I think simualting on the wave function of the universe itself, which follows sacred geometry and the geometric iteration of the platonic solids is the only way to really get to that level of information density, which will likely be fractal and holographic in nature.

    ‘ organic if you will’

    thoughts of the omega point come to mind, and our potential ability (getting quite fancy here with the imagination, even though theoretically possible) to one day control reality like a computer program–again, a seperate concept from quantum computation.

    But thats what springs up in my mind when I think of one day harnessing the power of  a quantum computer.

    yes, indeed, if in fact we were to harness quantum computation, matrix level realism may become a reality. That much computation, we may even gain insights on reality itself as mathematically we will be able to get a direct look at the ‘source code’ from an information theory perspective, of the universe. Seems like a long shot for now, but it may very well one day become possible (especially with ever more computing advances, which may shorten the timeline for a quantum computer considerably)
