Quantum Computers Explained – Limits of Human Technology

00:00

For most of our history, human technology consisted of our brains, fire, and sharp sticks.

00:06

While fire and sharp sticks became power plants and nuclear weapons,

00:10

the biggest upgrade has happened to our brains.

00:13

Since the 1960's, the power of our brain machines has kept growing exponentially,

00:17

allowing computers to get smaller and more powerful at the same time.

00:21

But this process is about to meet its physical limits.

00:25

Computer parts are approaching the size of an atom.

00:28

To understand why this is a problem, we have to clear up some basics.

00:33

In a Nutshell - By Kurzgesagt

00:39

A computer is made up of very simple components

00:42

doing very simple things.

00:44

Representing data, the means of processing it, and control mechanisms.

00:49

Computer chips contain modules, which contain logic gates, which contain transistors.

00:54

A transistor is the simplest form of a data processor in computers,

00:58

basically a switch that can either block, or open the way for information coming through.

01:03

This information is made up of bits

01:06

which can be set to either 0 or 1.

01:08

Combinations of several bits are used to represent more complex information.

01:13

Transistors are combined to create logic gates which still do very simple stuff.

01:18

For example, an AND Gate sends an output of 1 if all of its inputs are 1, and a output of 0 otherwise.

01:25

Combinations of logic gates finally form meaningful modules, say, for adding two numbers.
