Quantum Computing Definition



What is Quantum Computing?

Quantum computing is a field of computing that focuses on the development of computer technology based on the principles of quantum theory (explaining the behavior of energy and matter at the atomic and subatomic levels). Computers currently in use can only encode information with bits that take a value of 1 or 0, limiting their ability.

Quantum computing, on the other hand, uses qubits or qubits. It takes advantage of the unique ability of subatomic particles to allow them to exist in multiple states (ie, 1 and 0 at the same time).

Important point

  • Quantum computing is the study of how to use the phenomena of quantum physics to create new computing methods.
  • Quantum computing consists of qubits.
  • Unlike regular 0 or 1 computer bits, qubits can be a superposition of either of these, or both 0 and 1.
  • The power of quantum computers grows exponentially as the number of qubits increases.
  • This is different from traditional computers where the addition of transistors adds power only linearly.

Understand quantum computing

Superposition and entanglement are the two underlying functions of quantum physics in these supercomputers. This allows quantum computers to process operations exponentially faster and consume much less energy than traditional computers.

The field of quantum computing began in the 1980s. Later, it was discovered that certain computational problems could be addressed more efficiently using quantum algorithms than traditional problems.

Quantum computing can make significant contributions in the areas of finance, military, intelligence, drug design and discovery, aerospace design, utilities, polymer design, artificial intelligence (AI) and big data retrieval, and digital manufacturing. There is sex.

Its potential and projected market sizes are IBM, Microsoft, Google, D-Waves Systems, Alibaba, Nokia, Intel, Airbus, HP, Toshiba, Mitsubishi, SK Telecom, NEC, Raytheon, Lockheed Martin, Rigetti, Biogen, Volkswagen, Amgen.

According to Gartner, the percentage of large companies planning to create initiatives for quantum computing by 2025.

Quantum computer and classical computer

Quantum computers process information differently. Traditional computers use 1 or 0 transistors. Quantum computers use 1 or 0 qubits at the same time. The number of qubits linked to each other exponentially increases quantum computing power. On the other hand, if you link more transistors, the power will only increase linearly.

Classic computers are perfect for everyday tasks that need to be completed on your computer. Quantum computers, on the other hand, are ideal for performing simulations and data analysis such as chemical and clinical trials. However, these computers must be kept extremely cold. They are also much more expensive and difficult to build.

Traditional computing advances include the addition of memory to speed up computers. Quantum computers, on the other hand, help solve more complex problems. Quantum computers may not be able to run Microsoft Word better or faster, but they can run complex problems faster.

For example, Google’s quantum computer under development can be useful in many processes, such as speeding up machine learning training and creating more energy-efficient batteries.

Quantum computing has many other applications, such as sharing information securely. Other methods include fighting cancer and various health concerns such as cancer and the development of new drugs. Similarly, quantum computers help improve the ability to detect radar and missiles, aircraft, and more. Other areas include the use of quantum computing to keep water clean with environmental and chemical sensors.

Google proved in 2019 that quantum computers can solve problems in minutes, but traditional computers take 10,000 years.

Quantum computer example

Google (GOOG) is spending billions of dollars on plans to build quantum computers by 2029. The company has set up a campus in California called Google AI to help achieve its goals. Google has invested in this technology for years. Similarly, other companies such as Honeywell International (HON) and International Business Machine (IBM). IBM expects to reach major quantum computing milestones in the coming years.

Some companies are building (albeit expensive) personal quantum computers, but none are available on the commercial side yet. And with JP Morgan Chase and Visa investigating the technology, they are interested in quantum computing and its technology. Once development is complete, Google can launch quantum computing services over the cloud.

Enterprises can also access quantum technology without having to build a quantum computer. IBM plans to install 1,000 qubit quantum computers by 2023. At this time, IBM allows access to a computer if it is part of a quantum network. Some of the networks include research institutes, universities, and research institutes.

Microsoft also provides enterprises with access to quantum technology through the Azure Quantum platform. This is different from Google, which does not sell access to quantum computers.

FAQ about quantum computer

What is the company known as “Quantum Computer Services, Inc”?

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

How do you build a quantum computer?

Building a quantum computer is time consuming and costly. Google has been building quantum computers for years, spending billions of dollars. Google expects quantum computers to be ready by 2029, but IBM hopes to have 1,000 qubit quantum computers installed by 2023.

How much does a quantum computer cost?

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

How fast is a quantum computer?

Quantum computers are many times faster than classic computers and supercomputers. Google’s quantum computer, Sycamore, performed calculations at the 2019 IBM Summit that were 158 times faster than the fastest computers in the world.

Conclusion

Quantum computing differs from traditional computing in the way it works and in its uses. Quantum computing uses qubits, which can be 1 or 0 at the same time, while classic computers use transistors, which can only be 1 or 0. As a result, quantum computing is much more powerful and can be used for big data analysis or simulation. .. However, there is no commercially developed quantum computer yet.
