Quantum computing explained, 10 areas impacted by quantum

What is quantum computing?

Computing as we know it today is going to change radically. It's not a question of if, but when. Think of it this way; today's computers can get you from A to B on any street map. Tomorrow's quantum computers will have the power to navigate you through the universe.

This is made possible because computing will essentially be harnessing and exploiting the amazing laws of quantum mechanics to process information. Whereas a traditional computer uses long strings of “bits,” which encode either a zero or a one, a quantum computer uses quantum bits, or qubits.

A qubit is a quantum system that encodes the zero and the one into two distinguishable quantum states. Because qubits behave quantumly, quantum computing exploits the phenomena of "superposition" and "entanglement." (Hang on in there...)

These are the key concepts to get your head around when you think about the future of computing and communications technology.

Superposition is essentially the ability of a quantum system to be in multiple states at the same time — that is, something can be “here” and “there,” or “up” and “down” at the same time.

You will be familiar with the notion of a computer bit being "on" OR "Off". In quantum computing the qubit can be "on" AND "off" at the same time. 🤔

Entanglement is when two or more quantum particles are inextricably linked in perfect unison, even if separated by great distances. The particles are so intrinsically connected, they can be said to “dance” in instantaneous, perfect unison, even when placed at opposite ends of the universe.
