here Quantum Computing. You might have heard of it. People call it the future, they call it "amazing", a "breakthrough. They are right. But how does it work? Let's break it down.
First, the basics:
Classical Computers have bits. They only understand 1s and 0s, also known as "bits". No, they do not understand your Python, Java, C++, C, C#, Objective-C, or anything. They break it down into code...
For more in depth Frame of Essence has a really good video on this:
...and the CPU uses that.
Moving on to Quantum:
Quantum computers can use 1 and 0, and everything between 1 and 0. Like 0.39678394658824379653784305823487956324578435296748243679855625479856634 (just a random number).
The problem here is that once you measure them, they have a chance of collapsing into a 1 or a 0 (more on this here: https://en.wikipedia.org/wiki/Quantum_computing ).
This is why they are not as reliable as classical computers. But when cooled down to near absolute 0 (very low number) they are more reliable (for whatever reason).
Frame of Essence also has something on this.
Quantum Computing is complicated and this is a very short explanation with my knowledge, but it's something.
