What is a quantum computer? Explained with a simple example by YK Sugi

Hi everyone! The other day, I visited D-Wave Systems in Vancouver, Canada. It’s a company that makes cutting-edge quantum computers. I got to learn a lot about quantum computers there, so I’d like to share some of what I learned there with you in this article. The goal of this article is to give you an accurate intuition of what a quantum computer is using a simple example. This article will not require you to have prior knowledge of either quantum physics or computer science to be able to understand it. Okay, let’s get started. What is a quantum computer? Here is a one-sentence summary of what a quantum computer is: A quantum computer is a type of computer that uses quantum mechanics so that it can perform certain kinds of computation more efficiently than a regular computer can. There is a lot to unpack in this sentence, so let me walk you....
