First of all, to understand what quantum computing is and how a quantum computer will (possibly) impact our lives in the future, we need to compare it with a classical computer, and understand how it processes data. Classical computer and logic gates A classical computer operates with bits, that is, binary units of memory that can receive values 0 or 1. All information, including every character and pixel of light that is reaching your eyes right now, is stored on some electronic device (on your computer or in the cloud) in the form of these bits. More specifically, they can be processed through logic gates, that is, physical structures or a system that receives a set of these bits and returns another bit, 1 if the condition is satisfied or 0 if it is not. In the programming area, we call these functions Boolean operators (name given due to the studies of George Boole, who published very important works in algebraic logic). Briefly, there are 8 types of logic gates...
