What is Quantum Computing? Best Explanation 2022

Quantum Computing:

Quantum computing is a new technology that uses Quantum Mechanics to Address Issues that traditional computers cannot handle.

Only three decades ago, researchers began to think about the possibility of using genuine quantum hardware, which IBM Quantum now makes available to thousands of developers. These computers are vastly different from those that have been in use for more than half a century.

Understanding Quantum Computing

These supercomputers are based on two aspects of quantum physics: superposition and entanglement. As a result, quantum computers can perform operations at rates that are exponentially faster than traditional computers and consume far less energy.

Quantum computing was first developed in the 1980s. Quantum algorithms were more efficient at solving specific computer tasks than their conventional counterparts. Finance, military affairs, intelligence, drug design, aircraft design, utilities (nuclear fusion), polymer design, machine learning and artificial intelligence (AI), Big Data search, and digital manufacturing could benefit from quantum computing’s potential.

Some of the most well-known technology companies such as IBM, Microsoft, Google, D-Waves Systems, Alibaba, Nokia, Intel, Airbus, HP, Toshiba, Mitsubishi, SK Telecom, NEC, Raytheon, Lockheed Martin, Rigetti, Biogen, Volkswagen, and Amgen, are working on quantum computing because of its potential and projected market size.

Why Do We Need Quantum Computers?

Supercomputers aren’t all great for some situations. Classical supercomputers of different sizes typically have hundreds or even thousands of traditional CPU, GPU cores, and RAM. Scientists and engineers use these to solve challenging issues. But even the most powerful supercomputers have difficulty solving some types of problems.

Assuming the supercomputer is unable to tackle a complex problem, this is most likely because the large classical machine has been requested to do so. Complexity is frequently at blame when older computers don’t work.

Complex problems are those that include a large number of variables intertwined in a variety of ways. Because of the many electrons interacting with each other, it isn’t easy to model the behavior of individual atoms in a molecule. Determining the best routes for a few hundred tankers in a worldwide shipping network is also tricky.

Quantum Computer vs. Classical Computer

In quantum computers, information is processed uniquely. Computers of the past relied on transistors, which had a binary value of 1 or 0. More transistors can only improve power linearly by being linked together. Qubits, the fundamental building blocks of quantum computers, can be either 1 or 0. The more qubits joined together, the more powerful quantum computing becomes.

Classic computers best perform everyday chores that require the use of a computer. When it comes to doing simulations and data analysis, quantum computers are ideal. It is especially true for chemical or medicinal trials. However, extreme cooling is required for these machines. They are also more expensive and time-consuming to manufacture than other types.

Adding memory to speed up computers is a classic advancement in computing. More complex issues can be solved using quantum computers. While quantum computers may not be able to run Microsoft Word quicker or more efficiently, they are capable of solving more complex tasks.

Google’s quantum computer, for example, might be used to speed up machine-learning training or to make more energy-efficient batteries, among other applications. Other uses for quantum computing include encrypting and decrypting data. Other approaches include the development of new pharmaceuticals and the battle against cancer and other health problems. Additionally, quantum computers can assist boost radars’ ability to identify things like missiles and planes. Additionally, quantum computing can be used to maintain water purity via chemical sensors in the environment.

Real-World Example of a Quantum Computer

A quantum computer built by Google (GOOG) by 2029 will cost billions of dollars. Google AI, a campus in California, has been established to help the firm achieve its goal. Years of Google funding have gone into developing this technology. Many other businesses have followed suit, including HON and IBM. IBM hopes to reach significant milestones in quantum computing in the following years.

Even though a few businesses have created personal quantum computers, there is still no commercially accessible product on this site. For example, JPMorgan Chase and Visa are interested in learning more about quantum computing and its technologies. In the future, Google may offer a cloud-based quantum computing service.

Quantum technology can also be accessed without companies needing a quantum computer. According to IBM’s projections, a 1,000-qubit quantum computer will be in place by 2023. For the time being, IBM’s Quantum Network is the only way to gain access to its equipment. Participating entities in the network include academic institutions and government agencies.

Azure Quantum, a Microsoft-developed quantum computing platform, is also available to third-party businesses. This is an exception like Google, which does not sell access to its quantum computers.
