If the goal is to make quantum systems act like powerful classical machines, then today’s quantum computers may be too ...

The race to build larger and more powerful quantum computers has mostly focused on ...

Imagine a computer that could solve incredibly complex problems at a speed we can't yet fathom and bring about breakthroughs in fields like drug development or clean energy. That is widely considered ...

To predict when we’ll have a truly useful quantum computer, we need to know precisely what one is. Columnist Karmela Padavic-Callaghan finds that’s harder to pin down than you might think ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...
