What is Quantum Computing?

A lot of computer technologies had come up within the last couple of years but Quantum computing is by far the greatest paradigm shift on part of computer science developers.

At the time Quantum computers were proposed first in 1980 by Richard Feynman and Yuri Manin, It was highly criticized as due to limitations in modeling even simpler systems at that time. As time goes on during 1900 and 1925 it still had been a vital part of chemistry, condensed matter physics, and other technologies.

Simulating Quantum mechanics is hard to even to simulate. The simplest explanation could be like this that “A matter, at a quantum level, exists in a host of different possible states or configurations at the same time. Unlike, classical probability theory, which comes to a point that “every statistical experiment will contain elements that are equally likely to happen”, these many configurations of the quantum state, which can be potentially observed, may interfere with each other like waves. This interference prevents the use of statistical sampling to obtain the quantum state configurations.

Limitation in hardware is yet another factor to hinder in the path of quantum computing. Let us say a system of electrons can be in say any of 40 positions. We can, therefore, say that electron is in any of 2^40 configurations (since each position can either have or not have an electron). To store this state in system memory we would require around 130gb of memory. If next, we allow it to be in 41 positions, there would be twice as many configurations which may require around 260 Gb of memory to store the quantum state.

The core of quantum computing is to store information in quantum states of matter and to use quantum gate operations to compute on that information, by learning to “program” quantum interference. In future, we might be able to crack RSA and ECDLF using quantum computing.


Microsoft has taken a step by introducing “Microsoft Quantum Development Kit”, that will help in making quantum programming and algorithm development more accessible. Quantum programming is a distinct art from classical programming requiring very different tools to understand and express quantum algorithmic thinking. Microsoft has brought the Quantum Development tools to unlock the quantum revolution for their tasks, problems, and solutions.

Q# (Q Sharp) was designed to address the challenges of quantum information processing, it is integrated into a software stack that enables a quantum algorithm to be compiled down to the primitive operations of a quantum computer.
