A quantum computer is one of the most important phenomena of quantum mechanics to deliver huge leaps forward in processing power. This also one of the most promising applications of quantum mechanics in the future.
The applications and field of horizons of quantum computers promise to power exciting advances in various fields, from materials science to pharmaceuticals research. For example, there is a lot of research work is going on Companies experimenting with them to develop things like lighter and more powerful batteries for electric cars, and to help create novel drugs. Also, it can make a huge forward on fields like Cybersecurity
Financial Modeling
Cleaner Fertilization
Traffic Optimization
Weather Forecasting and Climate Change
Artificial Intelligence
Solar Capture
Electronic Materials Discovery etc.
The basic of computational capabilities and processing power behind a supercomputer is their ability to produce quantum bits or q bits. In quantum computing, a qubit or quantum bit is the basic unit of quantum information.it is actually the quantum avatar of the so-called classical binary bit which with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single photon in which the two states can be taken to be the vertical polarization and the horizontal polarization. But the main striking difference between in a normal classical bit and qubit is that a classical bit would have to be in one state or other, but quantum mechanics permit q bit to be in a coherent superposition of both state simultaneously.
So quantum computing is so much powerful to tackle some major problems. but it takes a couple more years for them to achieve their full potential. The main barrier in the field of quantum computing is the lack of skilled researchers in the field and lack of some key components and their suppliers. if we overcome this and put this exotic powerful machines live up to the promise it would definitely a huge leap to mankind and transform the entire outlook.
