Here's what quantum computing is and why it matters | Education 2.0 & 3.0 | Scoop.it
Researchers for IBM, Google, Intel, and others are in a fantastic scientific arms race to build a commercially viable quantum computer. They already exist in laboratories, and we’re only a few years away from the beginning of what may turn out to be an entire shift in how we think about computing.

A typical computer, like the one inside the phone or laptop you’re reading this on, is a binary system, basically a yes/no device. The most amazing thing about computer programmers is how they can take something as basic and simple as a computer chip and spit out something like Microsoft Office by creating a series of “if this, then that” scenarios. This showcases how useful the computer is as a tool for humans to accomplish tasks.

The quantum computer, however, is an entirely difference concept – the reason it’s quantum is that it doesn’t use binary logic. By its nature a quantum computer is a yes/no/both device. When a developer makes a logic choice they aren’t limited by “if this then that,” they can also ask “if this, then that — or both” and that makes all the difference in the world.
