## What is quantum computing and its advantages

*Before knowing the answer to what is a quantum computer, you answer my question, what is a supercomputer? On hearing the name of a supercomputer, the notion of such a computer will come to your mind, which can do any calculation in seconds, similarly, quantum computer speed If you have to search your phone number from the world's phone book database, then it will take at least 1 month for a supercomputer to find a number, whereas a quantum computer can do the same thing in hardly 20 minutes. *

*Looking at this, you can understand, how much is the speed of a quantum computer. Let us know what a quantum computer is? And how it works:-*

*what is a quantum computer?*

*The word quantum means, atoms can either be neutrons or protons that can be used to calculate or solve complex problems, computers that use them are called quantum computers. In these computers, instead of a computer chip, nuclear is used for calculation, the computer we are using now uses bits that are either saved in the database in the form of 0 or 1, while the atom is at a time. There can be both 0 and 1 which scientists have named qubit.*

*What is a bit in the computer?*

*A bit is a binary number in computer language, which takes only one number out of 0 and 1 at a time, just like we can turn an electric switch on or off.*

*Talking about classical computers, 8 bits can represent all the numbers between 0 and 255. Quantum computers can use 8 qubits to represent every number between 0 to 255 simultaneously if we use 100 qubits. If used, the quantum computer can calculate the number of atoms in the universe very easily.*

*What is a qubit in a quantum computer? *

*If we see at physics, the speed of the atom is not constant, at the same time it keeps on moving up and down, due to which it is not appropriate to give them a number, they can be both 0 or 1, due to which the reciprocal is not equal to a bit of the computer. Seeing this, scientists named it Qubit.*

*What is the difference between Bit and Qubit?*

*A bit is a binary number, which takes only one of the numbers 0 and 1 at a time.*

*Qubits are neutrons and protons, which can contain both (0,1) or 0 OR 1 at once.*

*How does quantum computing work*

*The quantum computer works on the principle of nature, like the mango tree planted in your house, which gives fruits automatically in every season, for this it does not need to ask anyone, in the same way, the quantum computer works, the atom is a natural cycle. *

*Work according to the way the compass automatically calculates the direction, sometimes it comes up and sometimes it comes down, in the same way, the atoms which we cannot see with our eyes sometimes go up and down at the same time, so they cannot be considered equal to bit, due to which they are called a qubit, which can be both 1 or 0 simultaneously, due to which their capacity is more than bit based supercomputer.*

*Bit = Taken(0) OR (1)*

*Qubit = Taken( 0) OR (1) OR Taken (0,1)*

*what is the calculation speed of the quantum computer?*

*Quantum computers do not do linear calculations like today's computers, such as Amazon company has to send its goods from Delhi to Mumbai to 5 addresses. The company wants that the time, as well as the distance, is minimum then today Quantum computers will calculate the shortest route to each address to find the answer to this question. Still, quantum computers will only select the answer, which will save a lot of time. It will take only 12 minutes to find it while the supercomputer will take 2 years to do the same work.*

*what is the difference between supercomputers and quantum computers*

*Supercomputers use the binary number system Bit.*

*Quantum computers use neutron and proton-based qubit systems.*

*Supercomputer takes one bit at a time either 0 or 1.*

*A quantum computer can take both 0 OR 1 OR (0,1) numbers at once.*

*The calculation speed of a supercomputer is less than that of a quantum computer.*

*Quantum computers are much more powerful than supercomputers.*

*Supercomputers do not have any working memory of their own.*

*Quantum computers have their own working memory, due to which they are faster than supercomputers.*

*what is quantum computing for example?*

**IBM Cloud-based quantum systems**

*20 quantum computers are being used by IBM company in its cloud-based application which is managing crores of transactions of the day or say crores of people whose speed is more than a supercomputer.*

* Advantages of quantum computing*

*Although (although) I have already said that, we have to work very hard to make Quantum Computer. But (but) nevertheless (nevertheless) IBM has given birth to a Quantum Computer with its hard work. As I have told you more than before that the Quantum Computer is much faster and much more intelligent than our present computers.*

*By the way, in our simple computers, Classical Algorithms are usually used. But (but) on the contrary, Quantum Algorithms are used in Quantum Computer, which will open any Task or application in a few seconds and do its work and give you the conclusion or output.*

*Here you must be feeling that it would be very easy and economical to make all these Algorithms. But (but) friends, it is not like this at all. Let me tell you for your information that yes, it takes a lot of hard work to make only one Quantum Algorithm. Along with this (furthermore) it also takes a lot of time to make these algorithms.*

*AT&T engineer Peter Shor created a Quantum factorization algorithm. This algorithm converts very large numbers into small prime numbers by factorizing them. The thing to note in this is that, here (here) Quantum computer has been able to do this kind of unprecedented work by using Quantum parallelism. After this (next) if we look at our ordinary computer, it will take 10.1 billion years to do this type of factorization work.*

*Conclusion*

*Here in this post, we add all related information about quantum computing like what is quantum computing, the advantages of quantum computing, and how quantum computing work then you should read our post till the end.*
