WHAT IS A QUANTUM COMPUTER:-

Quantum computers are machines that use the properties of QUANTUM PHYSICS to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform .Supercomputers,Classical computers, which include smartphones and laptops, encode information in binary “bits” that can either be 0s or 1s. In a quantum computer, the basic unit of memory is a (quantum bit) or QUBIT.

WHAT IS QUBIT :-

In quantum computing, a qubit or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics.

Qubits are made using physical systems, such as the spin of an electron or the orientation of a photon. These systems can be in many different arrangements all at once, a property known as quantum superposition. Qubits can also be inextricably linked  together using a phenomenon called quantum entanglement. The result is that a series of qubits can represent different things simultaneously.

For instance, eight bits is enough for a classical computer to represent any number between 0 and 255. But eight qubits is enough for a quantum computer to represent every number between 0 and 255 at the same time. A few hundred entangled qubits would be enough to represent more numbers than there are atoms in the universe.

WHAT IS QUANTUM COMPUTING:-

Quantum computing is an area of computing where it is focused on developing computer technology based on the principles of QUANTUM COMPUTER (which explains the behavior of ENERGY and MATERIAL on the ATOMIC and SUB-ATOMIC  levels). Computers used today can only encode information in bits that take the value of 1 or 0—"restricting their ability".

On the other hand quantum computing , uses quantum bits or QUBITS . It harnesses the unique ability of subatomic particles that allows them to exist in more than one state (i.e., a 1 and a 0 at the same time).

KEY TAKEAWAYS:-

1.Quantum computing is the study of how to use phenomena in quantum physics to create new ways of computing.

2.Quantum computing is made up of qubits. 

3.Unlike a normal computer bit, which can be 0 or 1, a qubit can be either of those, or a superposition of both 0 and 1.

4.The power of quantum computers grows exponentially with more qubits.

5.This is unlike classical computers, where adding more transistors only adds power linearly.

UNDERSTANDING THE QUANTUM COMPUTING:-

1.SUPERPOSTION and ENTANGLEMENT are two features of quantum physics on which these supercomputers are based. This empowers quantum computers to handle operations at speeds exponentially higher than conventional computers and at much lesser energy consumption.

The field of quantum computing started in the 1980s. It was then discovered that certain computational problems could be tackled more efficiently with quantum algorithms than with their classical counterparts.

Quantum computing could contribute greatly in the fields of finance, military affairs and intelligence, drug design and discovery, aerospace designing, utilities (nuclear fusion), polymer design, machine learning and artificial intelligence (AI) and Big Data search, and digital manufacturing.Its potential and projected market size have engaged some of the most prominent technology companies to work in the field of quantum computing, including IBM, Microsoft, Google, D-Waves Systems, Alibaba, Nokia, Intel, Airbus, HP, Toshiba, Mitsubishi, SK Telecom, NEC, Raytheon, Lockheed Martin, Rigetti, Biogen, Volkswagen, and Amgen. 

40% Percentage of large companies planing to create initiatives around quantum computing by 2025, per Gartner.

QUANTUM COMPUTER V/S CLASSICAL COMPUTER:-

1.Quantum computers process information differently. Classical computers use transistors, which are either 1 or 0. Quantum computers use qubits, which can be 1 or 0 at the same time. The number of qubits linked together increases the quantum computing power exponentially. Meanwhile, linking together more transistors only increases power linearly.

2.Classical computers are best for everyday tasks that need to be completed by a computer. Meanwhile, quantum computers are great for running simulations and data analyses, such as for chemical or drug trials. These computers must be kept ultra-cold, however. They are also much more expensive and difficult to build.

3.Classical computing advances include adding memory to speed up computers. Meanwhile, quantum computers help solve more complicated problems. While quantum computers might not run Microsoft Word better or faster, they can run complex problems faster.

FOR EXP:- Google’s quantum computer that’s in development could help with many processes, such as speed up machine-learning training or help create more energy-efficient batteries. for more info get into this link 

4.Quantum computing has a number of other applications, including securely sharing information. Other methods include fighting cancer and various health concerns, such as cancer and developing new drugs. As well, quantum computers can help improve radars and their ability to detect such things as missiles and aircraft. Other areas include the environment and using quantum computing to keep the water clean with chemical sensors.

FOR EXP:- Google, in 2019, proved that a quantum computer can solve a problem in minutes, while it would take a classical computer 10,000 years.

REAL WORLD EXAMPLE OF A QUANTUM COMPUTER:-

Google (GOOG) is spending billions of dollars on its plan to build its quantum computer by 2029. The company has opened a campus in California, called Google A.I to help it meet its goal. Google has been investing in this technology for years. As well, so have other companies, such as Honeywell International (HON) and International Business Machine (IBM). IBM expects to hit major quantum computing milestones in the coming years. 

While some companies have built personal (although expensive) quantum computers, there is still nothing available on the commercial side. And there’s interest in quantum computing and its technology, with JPMorgan Chase and Visa looking into the technology. Once developed, Google could launch a quantum computing service via the cloud. Companies can also gain access to quantum technology without having to build a quantum computer. IBM plans to have a 1,000-quibit quantum computer in place by 2023. For now, IBM allows access to its machines if they’re part of its Quantum Network. Those that are part of the network include research organizations, universities, and laboratories. Microsoft also offers companies access to quantum technology via the Azure Quantum platform. This is unlike Google, which doesn’t sell access to its quantum computers.

QUANTUM COMPUTER FAQ'S:-

1.What Company Was Known as "Quantum Computer Services, Inc"?

America Online (AOL) was formerly known as Quantum Computer Services Inc. AOL first started as Quantum Computer Services in 1985. The company was started by employees from the Control Video Corporation (CVC).

2.How Do You Build a Quantum Computer?

Building a quantum computer takes a long time and is expensive. Google has been working on building a quantum computer for years and has spent billions of dollars. Google expects to have its quantum computer ready by 2029, although IBM hopes to have a 1,000-quibit quantum computer in place by 2023.

3.How Much Does a Quantum Computer Cost?

To build, quantum computers still cost billions. However, China-based Shenzhen SpinQ Technology plans to sell a $5,000 desktop quantum computer to consumers for schools and colleges. Last year, it started selling a quantum computer for $50,000.

4.How Fast Is a Quantum Computer?

A quantum computer is many times faster than a classical computer and even a supercomputer. Google’s quantum computer, Sycamore, is said to have performed a calculation in 200 seconds that one of the world’s fastest computers, IBM's Summit, would take 10,000 years to solve.9 IBM disputes this claim, saying it would take 2.5 days-still more than 1,000x slower than Google's quantum machine.
