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.

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, ...

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 ...

Computer scientists at UC Davis, Maynooth University and Caltech have created DNA molecules that can self-assemble by carrying out a Boolean logic computation. Highlighted in green is the ...

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 ...

The awesome Digirule 2U is a small 8-bit programmable binary computer created by developer Bradley Slattery. Launched via Kickstarter this month, the project is coming to the end of its campaign with ...

Researchers have developed a small quantum computer that is capable of running multiple algorithms. The breakthrough hinges on the ability to program quantum bits or 'qubits' with software, and paves ...

The Raspberry Pi has been a huge success story for Britain, giving millions of people an affordable way to tinker and learn with pocket-sized hardware. Now, the BBC is hoping to make a similar impact ...

Five on a line: an ion trap with four segmented blade electrodes used to trap a linear chain of atomic ions for quantum-information processing. Each ion is addressed optically for individual control ...

There comes a moment in every physicist’s life when they think the unthinkable: I wish I were an engineer. I suspect this thought crossed the minds of the 14-odd physicists involved in creating a key ...

Hackaball a new children’s programmable computer ball has been launched over on the Kickstarter crowdfunding website this month and has just entered into its final week of funding and has already ...
