Let me do a simple definition before we continue on this post about quantum computing, how they work and the importance of quantum computing in the future.
What is physics?
Physics is the science that studies the behavior and motion of object matter through space and time. It is the study of everything that governs the physical world we live in.
What is quantum mechanics?
The field of physics that study the behavior of tiny and microscopic part of the universe at the subatomic level.
Quantum Superposition
This is the quantum state in which two particle can be at two state at the same time.
Quantum Entanglement
The relationship between two particles in superposition where the state of one particle determines the state of the other.
What does Quantum Physics have to do with computing?
Currently computer uses binary bits to access information. This bits are either in zeros or one but with the effect of quantum computing which turns bits to qubits, computer can now process information in either 1, 0 or both giving it the ability to handle larger data. Quantum computers have the ability to solve problems that could take infinite years for a classical computer to solve because of the binary bits and the quantum bits.
Accurate modeling ha applications for engineering, medicine, energy production and much more. We could model the reality for the first time. - Richard Feynman
A normal computer bits is made from transistors but for quantum computers, the qubits is made from anything that exhibits quantum properties, this could be an electron, molecule and an atom. With quantum computers, coding the rules of physics into the way atom interact will be possible. Calculation with a classical computer can be very difficult or impossible for a few molecules. Modeling a compound like Calcium monofluoride (CaF) could be relatively impossible for a classical computer but with quantum computing, it can easily model this as the computer itself operates in superposition.
Use of Quantum computing
Unlike classical computers solving macro problems, quantum computers are used to solve problems related to small input and output, or problems that has infinite possibilities. Unlike classical computers, quantum computers can calculate the possibilities of what happens between the times when a molecule react and produces result.
Quantum computers can be used to break/solve equations that rely on the factorization of large numbers thereby being able to break encryption.
Solving problems in real life and different field of studies including distance of locations in geography faster and with different possibilities.
hi @papa-mensa
It is an interesting topic and I wonder when we will really see useful quantum computers. I think when they do become more than academic research but really powerful then it will change the world of computing. Especially in the world of cryptography. However, I think we are still quite a few years away for it to be a serious threat.

I think with the way technology is going, we might see it in action sooner than we think. Thanks for the comment.

I hope so, we could do with some good breakthroughs in technology :-)

This topic appears very technical and I am sure it is not something for babies (smiles), I am not really good with physics so I see those who can analyze the field as a genius.

I am sure you will understand when it becomes a reality and paper work.
Thank you for the comment.
