Quantum Computing

Before we talk about quantum computers, let's look at what quantum theory is.

The atom is the basic building block of matter.

The atom is made up of tiny subatomic particles such as electrons, protons, and neutrons.So in an environment with subatomic particles like this, these particles behave strangely.

Predicting these behaviors is what happens in quantum science.

Quantum theory

Quantum theory was first proposed by Max Planck.Also Irwin Schrdinger and Albert Einstein have contributed to these investigations.

There are three basic theories of quantum theory.

1.Superior theory

2. Theory of inconsistency
3. Tangle theory

Simply put, these three are ....

1.Superior theory

This is about a state between yes and no. To illustrate this, Schrodinger has proposed a model called the cat concept test.Something like this is happening here,

A flask filled with a poisonous substance is placed in a chamber containing a radioactive medium.

There is a cat inside this chamber. There is also a meter that shows the radiation level in the chamber.
The device is designed to release the radioactive material by breaking the poison flask with a switch that activates the release of the radioactive material.

Right now, imagine that the poison is released in that way

Now someone looking at this cat seems to be alive.A little further on, the cat appears dead.There is another possibility between these two cases.That's when the cat is not alive or not dead.Quantum corresponding between yes and no.

The Superior theory explains that there is such an opportunity.

2. Theory of inconsistency

Suppose a particle is somewhere, and then we see that particle, and where it is.Now if the nature and location of this particle is constantly changing ...... 

Now at some point if someone asks about the location and nature of this particle we can not tell about it right?
This is what is called quantum inconsistency in quantum theory.

3. Tangle theory

Suppose a particle exists in a quantum state.And there's another particle a long way from the first particle,No matter how far apart they are, they can interact with each other without interrupting this distance.

This is what is called tangle theory.This was presented by Mr. Albert Einstein.He said that these particles interact with each other like ghosts.Now you have a delta size idea of ​​the basics,Now let's see how quantum relates to computer technology,

Quantum computer

The power of the digital computer depends on the microprocessor in it.Early computers were machines as large as rooms.those have very low efficiency.This is due to the large size of transistors available.Later, these transistors with valves were molded onto a silicon sheet and reduced to a microprocessor.
In time, the transistor was further compressed, making computers much smaller, more powerful, and more efficient with microprocessors.These are the computers we currently use.The last step in minimizing the processor in this way is to minimize it to the subatomic stage.
That is the dawn of the quantum computer age.

Typical computers vs quantum computers

A typical computer represents data using one and zero states.But as mentioned earlier, there is a middle ground (1/0) between these two cases in quantum computers.That is, in quantum computers, there are three states to represent data.
Furthermore, a quantum computer can perform a number of calculations at a time because the data in the quantum state can be located in multiple instances.
In that sense, a quantum computer can do hundreds of thousands of tasks in less than an hour comparing to typical computer.
That's why these computers are used to build a variety of software, space data analysis, flight control, meteorological analysis and many other things.
There are already several computers of this type working in different places of the world.
NASA's D-wave Two is a good example of this.
I think you have a little idea about quantum. See you soon in another post.
