Quantum computer breakthrough?

IBM unveils world's first commercial quantum computer

IBM's new quantum computer is a symbol, not a breakthrough

In the grueling race to build a practical quantum computer, tech companies are keeping their spirits up by loudly cheering every milestone - no matter how small. One of the most vocal competitors is IBM, which today at CES unveiled the IBM Q System One: a 20-qubit quantum computer that's built for stability, but with some very flashy design.

IBM is touting the Q System One as "the world's first fully integrated universal quantum computing system designed for scientific and commercial use.

Quantum computing: A simple introduction

How can you get more and more out of less and less? The smaller computers get, the more powerful they seem to become: there's more number-crunching ability in a 21st-century cellphone than you'd have found in a room-sized, military computer 50 years ago. Yet, despite such amazing advances, there are still plenty of complex problems that are beyond the reach of even the world's most powerful computers-and there's no guarantee we'll ever be able to tackle them.

One problem is that the basic switching and memory units of computers, known as transistors, are now approaching the point where they'll soon be as small as individual atoms. If we want computers that are smaller and more powerful than today's, we'll soon need to do our computing in a radically different way. Entering the realm of atoms opens up powerful new possibilities in the shape of quantum computing, with processors that could work millions of times faster than the ones we use today. Sounds amazing, but the trouble is that quantum computing is hugely more complex than traditional computing and operates in the Alice in Wonderland world of quantum physics, where the "classical," sensible, everyday laws of physics no longer apply. What is quantum computing and how does it work? Let's take a closer look!

IBM unveils world's first commercial quantum computer

IBM has unveiled the world's first commercial quantum computer in a breakthrough that could someday lead to PCs that are millions of times faster than a regular machines.

Named the IBM Q System One, the supercomputer was unveiled this week at the Consumer Electronics Show (CES) in an airtight 9-foot cube made from half-inch thick glass.

The IBM Q uses theories of physics to create computing techniques that are far more powerful than current devices.
