We step inside a quantum computer lab to answer your questions about technology that promises to revolutionise everything from particle physics to fertiliser production.

Also this week on Tech Life: lots of us upload and download large quantities of data, and the expectation is that the demand for data will only increase in the future. How will our current networks cope ? The solution travels at the speed of light.

And how do you teach AI to speak in different accents ? We find out.
