Quantum Mechanics
Quantum computing is an emergent field of cutting-edge computer science harnessing the unique qualities of quantum mechanics to solve problems beyond the ability of even the most powerful classical computers. In, 1981 the professor Richard Feynman expressed about quantum system like atoms are based upon quantum laws and this are so complicated that we cannot express it in terms of binary language, for understanding we need a computer which is based upon quantum laws. The most famous dialogue of Feynman is " Nature is not classical and if you want to make a simulation of nature you better make it quantum mechanical." Fayman also proposed some awesome theories that we use transistors as binary language while on means 1 and off means 0 he proposed that we can use electrons like up spin means 1 and downspin means 0. Then how the computers will become powerful. The two towers of quantum mechanics Quantum Superposition and Quantum Entanglement The main experiment of Quantum Computers is Double Slit Experiment.
The Double Slit Experiment is an experiment done by physicist. Imagine there were two parallel slits on straight plate and a ray of light is passed through it the image on the screen formed is a pattern of two parallel lines, in the place of light suppose we pass subatomic particles like if we fire electrons or protons, we will see the interference pattern and this pattern will make waves the behavior of it is like that it will collides with each other from this we can understand that these particles behave like waves. If we observe one particle being in one quantity passes through two slits this property is known as Superposition. One particle being in one state but in different positions. If we use this property of Superposition in multiple combinations of algorithms or computing. Again, if we observe one wave is splitting into two waves then these waves will interact with each other. There are two types of Interferences Constructive and Destructive. Constructive interference is a type of interference where two waves of same size and structure combine with each other, so it is bright image. If two are colliding with each other or getting cancel out, then it is called Destructive interference. We can understand that we can't pinpoint the exact position of the particle, means wave nature is not deterministic, but it is probabilistic. From we understood that Quantum world is based of probability from then this world was not so hotchpotch. Like in 1900's Max Born has introduced his own formulae for guessing the position of a particle. If we use this technology in computers in like a question in which there are trillions of options but only one is correct like corrupting a server and so on.
This technology is used in computers in the place of transistors. In quantum computers we use electron spin like spin up means one and spin down means 0. Imagine there was a maze in which there are a thousand routes but only one is correct in normal computers the transistors should go to the end of the route and check in case of quantum computers using the property of superposition one particle can travel at the same time means two particles 4 routes. The no of routes is 2 power number of particles.
After scientist discover this technology then world will change a world which we can imagine, first things first human we become deathless new medicines will discover we can finally make pandemics less powerful. Now we can extend life up to !50 years without any inconvenience. We know that universe also depend on these laws only know and if we model these laws and we can solve complicated physics like black holes and anti-gravity can be learned up to the point. Even we can solve the mystery of Dark energy and Dark matter and finally we can search for the alien life. AI will be developed, and we can discover whatever till our imagination goes on.
