Computing faces an energy crunch unless new technologies are found

The energy required to power the massive, factory-sized data centres that computers rely on already consumes 5% of global electricity. And that energy load is doubling every decade.

How to make computers faster and climate friendly

The Internet of Things is contributing to climate change. Innovation in computer design could help mitigate the problem.

Error correcting the things that go wrong at the quantum computing scale

One of the challenges for quantum computing is knowing how to detect and correct errors that may occur in the data. And we can do that without even knowing what the data says.

How quantum mechanics can change computing

As companies make quantum computers available through their cloud services, take a look at what it means for computing to move beyond classical mechanics and into quantum physics.

Welcome to Lab 2.0 where computers replace experimental science

Developing new technologies requires time-consuming, expensive and even dangerous experiments. But now we can carry out many experiments entirely on computers using modelling.
