For a classical computer to function we have to combine different bits (existing in either an on or off state) and transistors together. At the very fundamental level, all quantum computers use a transistor, a transistor can be in one of two states the on or off state, in computer terms we’ll say 1 or 0, this information of the state is what we call a bit( the smallest unit of information inside a computer).
To define a quantum computer, let us first understand what classical computers are. That definition confused me as well, so let me try to write it my own words. Quantum computing is computing using quantum-mechanical phenomena, such as superposition and entanglement. I would avoid using some big physics terminologies in this article and try to explain in simple terms, so let’s get to it. What are the available tools for Quantum Computing today? What areas would quantum computers affect what we do? 3. In this article, I would be attempting to answer 4 major questions asked when the subject of quantum computing comes up. By classical computers I mean electronic devices like our laptops, phones, etc. So why should I even study about it today? My answer is simple, it’s going to be a big game changer in the world of computing as we know it, Microsoft's research lab predicts that quantum computers would begin to replace our classical computers in the next 10 –15 years. In the nearest future, quantum computers would change our world drastically.
Technology has advanced significantly in recent years, our mobile phones have become more powerful than the computer NASA used to put man on the moon and it gets better by the day. Quantum computing is becoming one of the most talked about new technology even though it does not fully exist yet.
