The Dawn Of Quantum Computing

The conventional digital computers can solve many of our day-to-day problems, but they are only used for limited applications. Programmed with code, they take a long time to solve massive real problems.But the Quantum computers are incredibly powerful machines that take the approach to processing information to a higher level. These Quantum Computing machines are built on the principles of quantum mechanics, they exploit complex and fascinating laws of nature.

Today's computers transform long series of ones and zeros — called bits to represent the information. Quantum computer use quantum bits, or qubits, to encode information as 0s, 1s, or both at the same time, this superposition of states. Each qubit could take a superposition of both 0 and 1. Thus, the number of computations that a quantum computer could undertake is 2^n, where n is the number of qubits used. A quantum computer comprised of 500 qubits would have a potential to do 2^500 calculations in a single step. That's more than the number of atoms present in the known universe.The digital computers today or even parallel processors, still only truly do one thing at a time: there are just two or more of them doing it. By harnessing such power, quantum computing can run new types of algorithms to process information more holistically.

This capability means that an eight quantum bit computer can be in a superposition of 256 different states. There is, however, a problem that these “states” represent only possibilities. To get a quantum computer to focus on a single answer is a very complicated real-world problem. When the quantum computer is being used to answer a quantum question, such as how the human body interacts with a new drug, this focusing happens automatically. But in other cases, such as when a quantum computer is used to answer a classical question, major difficulties arise.

Like the first digital computers, quantum computing offers the possibility of technology millions of times more powerful than current available systems, but the key to success will be translating real-world problems into the quantum language. In a decade or in the next century, we’ll likely be able to access them in the cloud and they will help us solve problems that seem impossible today.They will lead us to revolutionary breakthroughs in fields of healthcare, industry and scientific research, the optimization of complex man-made systems, and artificial intelligence.The Quantum Computing is going to revolutionize the computing, and it is going to happen faster, this will open doors to the higher levels of computing.
