Researchers from Brown University and the University of Michigan have achieved something that scientists had only imagined until now. By carefully arranging tiny particles of silver into custom-built structures, they created and stabilized a previously elusive state of matter that had existed only in theoretical models.

In Greek mythology, cutting one head off the Hydra of Lerna simply resulted in two more heads growing to replace it – and it turns out it’s even worse for photons. If you try to cut a piece off a particle of light, the result is infinitely many more of them being created.

Quantum computers today are notoriously difficult and expensive to operate. Most require temperatures near absolute zero, about -459 degrees Fahrenheit, to maintain the fragile quantum states needed for computation and communication.

Toone knew that hours after every match, she would always get a phone call from Nick.

He and her mum, Karen, would always come to watch Toone's matches, but Nick also recorded them on TV so he could have another look when he got home before calling his daughter for a "debrief on the whole game".
