A faster method to read quantum memory

The potential computing revolution that quantum computers have long promised is based on their weird property called superposition. Namely, qubits can take both logical states 0 and 1 simultaneously, on top of any value in ...

Quantum strangeness gives rise to new electronics

Noting the startling advances in semiconductor technology, Intel co-founder Gordon Moore proposed that the number of transistors on a chip will double each year, an observation that has been born out since he made the claim ...

Light up logic: Engineers perform computational logic with light

For the first time, researchers have performed logic operations with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods open up research possibilities, including low-power, ...

When electric fields make spins swirl

We are reaching the limits of silicon capabilities in terms of data storage density and speed of memory devices. One of the potential next-generation data storage elements is the magnetic skyrmion. A team at the Center for ...

Software finds the best way to stick a Mars landing

Selecting a landing site for a rover headed to Mars is a lengthy process that normally involves large committees of scientists and engineers. These committees typically spend several years weighing a mission's science objectives ...

Control system simulator helps operators learn to fight hackers

A simulator that comes complete with a virtual explosion could help the operators of chemical processing plants – and other industrial facilities – learn to detect attacks by hackers bent on causing mayhem. The simulator ...

Using nanowires to build all-optical logic gates

A team of researchers at Aalto University in Finland has found a way to use nanowires to build all-optical logic gates—a major step toward building a light-based computer. In their paper published in the journal Science ...

Artificial intelligence saves water for water users associations

Agriculture uses 70 percent of the water in the world, and this appears to be an upward trend regarding water needs. As the demand in other industry sectors is also increasing, and the effects of climate change exacerbate ...
