Using a few ultracold ions, intense lasers and some electrodes, researchers have built the first programmable quantum computer. The new system, described in a paper to be published in Nature Physics, ...

Excuse me a moment—I am going to be bombastic, over excited, and possibly annoying. The race is run, and we have a winner in the future of quantum computing. IBM, Google, and everyone else can turn in ...

The memristor array chip plugs into a custom computer chip, forming the first programmable memristor computer. The team demonstrated that it could run three standard types of machine learning ...

Here’s a way to play around with simple computing concepts without going too crazy with the hardware side of things. [John Eisenmann] calls it the DUO tiny. It’s a programmable computer based around ...

Scientists have developed a number of quantum computing systems that use ions or electrons as bits of data; mathematical "operations" can be performed on them with beams of light or electrical pulses.

The quest to build a powerful quantum computer is one of the great challenges of 21st century physics. And although the hurdles are significant, physicists are chasing them down, one by one. They’ve ...
