Explainer: What is quantum machine learning and how can it help us?

Artificial intelligence refers, among other things, to machines' capacity to demonstrate some degree of what humans consider "intelligence". This process is being driven by the rapid advancement of machine learning: getting ...

Boosting the 'brains' of computers with less wasted energy

Many internal components used in today's computers reach temperatures that are hot enough to cook a Thanksgiving meal. The heat produced by the computations can easily burn human skin and tissue – and much of the heat is ...

Computer

A computer is a machine that manipulates data according to a set of instructions.

Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into a wristwatch, and can be powered by a watch battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". The embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are however the most numerous.

The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a mobile phone to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity.
