What is Quantum Computing?

A quantum computer operates on the principles of quantum theory and is based on computer technology. On a quantum level (atomic and subatomic), quantum theory explains how energy and matter behave. Specific computation tasks can be performed with quantum computing by combining bits. Compared to their classical counterparts, all of these are much more efficient. Providing massive performance gains for specific use cases, quantum computers mark a major leap forward in computing capability. Simulations, for example, are one of the strengths of quantum computing.

By allowing bits to be in multiple states at once, quantum computers gain much of their processing power. Combining 1’s, 0’s, and both a 1 and a 0 is one of their capabilities. Los Alamos National Laboratory, MIT, IBM, and Oxford University are some of the current research centers in quantum computing. Through cloud services, developers can also access quantum computers.

Finding the essential elements of quantum computing was the first step. Paul Benioff invented a quantum the mechanical computer at Argonne National Laboratories in 1981. A major contribution to quantum computing research was made by David Deutsch of Oxford University. A few months after publishing a breakthrough paper, he wondered if it was possible to design a computer-based solely on quantum rules.

What is quantum computing used for? 

Here are a few ways that quantum computing can be used. Organisations can access cloud-based quantum computing through incentives like IBM Quantum Service. Is there any way that it can be used for something else? In the following sections, we will highlight a few current and potential applications of quantum computing: 

Molecular modeling

The simulation of atoms and molecules with current supercomputers is difficult. Simulating quantum physics using quantum computing could provide insights into how batteries work and how proteins interact, advancing energy storage and medicine. 

Database searching.

With quantum computers solving problems in a different way than traditional computers, massive amounts of data could be stored and searched much quicker. 


Cryptography could be broken by a fully functioning quantum computer, which would pose a huge threat to cyber security. It is still being worked on creating quantum-proof cryptography, however. Cybersecurity and network security may benefit from quantum computing. 

Weather forecasting

Forecasting requires vast amounts of data and a variety of variables in meteorology. It is difficult for supercomputers to predict the weather with much accuracy. We could be able to predict the weather with more complexity by using quantum computing. 

What is the future of technology if quantum computing is adopted? 

We are still in the early stages of quantum computing. It is still difficult to harness the technology and there are many unknowns, as we’ve seen. In spite of this, quantum computers could revolutionize our understanding of the world. 

Quantum computers are capable of modeling and simulating complex data, as well as solving problems much faster. The question remains whether we are capable of realizing that potential completely. Since Google and IBM are heavily invested in technology, we can expect to see further development in the near future.
