Historical View of Quantum Computing:

As we know, the first computer was invented in 1822 by Charles Babbage. The Quantum computer was first established in the 1980s by Richard Feynman and Yuri Manin. While quantum mechanics was introduced in the era between 1900 to 1925.

How we can define Quantum Computing:

Quantum computing is actually based on quantum theory which explains the nature of energy on atomic and subatomic level. It can process through low level language (0|false and 1|true). Quantum computing performs its actions by operations 0 and 1 and both at the same time. In Some modern theories, it may be considered that the time in quantum would pass much slower relatively in the real world. So, according to this concept quantum computing can perform operations more quickly.

How it does work:

Quantum computing works with a binary system which mean’s 0 and 1 operations. Quantum computers quickly differentiate between true and false algorithms and they can perform both operations simultaneously. These computers work with qubit stands for quantum bit and the result is based on the qubit’s state immediately. 

Eligibility Criteria:

Quantum computing is a high-speed device. It can solve problems in a very short time period on a relatively supercomputer. Quantum computing solves the problems in just 4 minutes, which is a super computer that takes 10,000 years. But this advanced development cannot be replaced by a super computer. The reason is that no doubt quantum computers are most eligible but it is not sufficient for doing random tasks like office work and emailing. 

Which companies work on Quantum Computing:

• Baidu
• IBM
• INTEL
• Microsoft Azure
• Toshiba 
• D-Wave System
• Quantum Computing lnc
• Xanadu

Why is it important for the future:

First of all, we need to know why it was needed? The current generation is related or connected with supercomputers. Which can perform tasks on binary functions 0 and 1. Supercomputers perform one operation at one time 0 or 1. But the main thing which differentiates Quantum computing from supercomputers is that, quantum computing performs both operations 0 and 1 simultaneously which is called Superposition. They can more efficiently save data which is highly demanded by people. It can also play a vital role in Cybersecurity agencies. They can save data in qubits, not in bites which increase the demand of quantum computing.

Advantage and Disadvantage of Quantum Computing:

Each type of technology has positive and negative impacts which can affect the people’s well being by directly and indirectly. So here we discuss some pros and cons of quantum computing. 

Advantages Of Quantum Computing

Safe data:

Quantum computing makes its own cryptographic algorithms like symmetric, asymmetric, hash functions that are doing their best to save data. It is able to weaken other asymmetric functions. 

Protection from harmful threats:

Supercomputers cannot weaken the encrypted threats quickly as Quantum computing breaks the encrypted functions in just a few mere seconds.

Booster speed:

Quantum computers must be able to solve difficult problems in just seconds. The speed of these types of computers is measured in qubits. They highly speed computers as they work 10,000 years in just 4 minutes. This can be estimated at the speed of quantum computers. 

Superposition:

Supercomputers perform one task or operation at one time like true or false, yes or no, 0 or 1. On the other hand, supercomputing performs both tasks or operations simultaneously, this is called the superposition. 

Disadvantages Of Quantum Computing:

Error detection:- 

Error detection is the most challenging problem in quantum computing. If some types of error can occur in programming or in calculations it is more difficult to find or solve it. It is possible that it can break through the computational calculations. So, we cannot neglect this defect. 

Intervention:

This means that quantum computing cannot permit the outer bond things to interfere in it. If external interventions occur it can collapse quantum computing. 

Data Corruption:

Quantum computing cannot permit recovering data because data may be saved in the form of waves. So, it is impossible to recover data which is the biggest disadvantage of this advanced technology.

Financially High Cost:

In developing quantum computing IBM bears a high cost which is $16.4 billion. It is just the cost of one company but at that time a large number of companies invested in developing the most advanced technology. If they are successful in developing quantum computers, obviously a revolution is to be made in the technological industry.  

Random Features Of Quantum Computing: 

1. Quantum Computing based computers are more powerful computers rather than normal computers. 
2. It saves data in qubits but not in bites.
3. These types of computers are used at a very high level like at the state level, international level, and for multinational companies.
4. It is more efficient to solve complex problems.
5. Supercomputers take 10,000 years to solve a problem as the same type of problem quantum computers just solve in 4 minutes. 
6. These are really expensive types of technology.
7. They are eligible to cheat the natural world.
8. Quantum computers understand Artificial Intelligence in just a few seconds. 

Why Google prefers Quantum computers rather than Classical computers:

Quantum computers have high speed to perform several difficult tasks. In Oct 2019, Google Artificial Intelligence collaborated with U.S NASA to develop quantum computing. In 2019, Google argued that it’s Sycamore quantum computer which completed a task in just 200 seconds that would take a classical computer 10,000 years. Sycamore has 53 qubits. Google invested millions of dollars to develop quantum computers. The main aim of Google to develop quantum computing is to increase the speed of saving data or perform several difficult tasks without errors. So, Google prefers quantum computing rather than classical computers.

How it build its niche in technical field:

As we discussed above Quantum computing works with superposition and entanglement which means both operations 0 and 1 work at the same time. We don’t know which functions are performed first. On the other hand, supercomputers, which are the fastest technology of the earliest generation, also work with binary language and it can complete a task at a time. But quantum computing performs multiple difficult tasks completed at a time. This is the biggest reason to increase the passion of developing the quantum computing.

To be conclude that: 

Quantum computing is the biggest need for current and also for future generations. The idea of this most advanced technology made a revolution in the technical field. In 2030, there will be 200 to 500 quantum computers available in the rest of the world. Large number of technological related companies still invest or work to construct it because now it has become necessary.
