What is Quantum Computing?
Quantum computing is an area of computing that focuses on developing the technology of computer science on the basis of the principles of quantum theory(which explains the behavior of energy and material on the atomic and subatomic levels.) The computers that are used today in Schools, Colleges, Homes, and Offices can only encode data in bits that only take the value of 0 or 1. On the other hand, Quantum computing uses quantum bits or qubits. It has the unique ability that allows them to exist in more than one state. i.e, a1 and a0 at the same time.
The quantum computing field started in the late 1980s. Then it was found that certain computational problems could be tackled more efficiently with their quantum algorithms. Quantum computing could greatly contribute to the fields of finance, military affairs, intelligence, drug design and discovery, aerospace designing, machine learning, and artificial intelligence (AI).
Quantum computing has great potential that the biggest tech companies like IBM, Microsoft, Google, Alibaba(Shopping website), Intel, Nokia, Hp, Airbus, Toshiba, and many more are working in this field. Quantum computers process data differently from classical computers. As the classical computers encode data in bits that either be 1 or 0 but quantum computers use quantum bits or qubits, which can be 1 or 0 at the same time.
As we know that quantum computers are powerful but that doesn't mean that the classical computers which are been used in schools, colleges, homes, and offices are worthless. Classical computers are best for the everyday tasks that needed to be completed by a computer. Quantum computers are great for multiple calculations at a time and data analyses for chemical trials.
As we have discussed above the differences between Quantum computers and Classical computers, I want to add some more lines that quantum computers are very much expensive, difficult to build, and are not for everyone. Classical computers advances include adding more memory(RAM) to speed up computers. Quantum computers cannot run Microsoft Word better or faster than classical computers, they can solve complex problems faster than classical computers. Quantum computers must be kept in an ultra-cold environment.
Google (GOOGLE) 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 AI, 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. IBM plans to have a 1,000-qubit quantum computer in place by 2023. America Online (AOL) was formerly known as Quantum Computer Service Inc. AOL first started as Quantum Computer Services in 1985.
