How quantum computing got a boost from an experiment in a cornfield

In a cornfield in India, Urbasi Sinha ran an experiment that may challenge the rules of quantum mechanics and paves the way for higher dimensional quantum computing

So, what do you do?

I work with photons, investigating their use as building blocks for quantum technologies. These could revolutionise our lives due to their promise for exponential speed-ups in computing and unprecedented security in communications. One of our current projects involves quantum communication between two continents using a satellite.

The triple-slit experiment sounds interesting, what is it?

The double-slit experiment shows that photons act both as waves and as particles, but it also suggests that a single photon passes through both slits at the same time, a phenomenon called superposition. We devised a way to …
