Researchers have transferred 'quantum' information between computer chips at record speeds and accuracy.
Twenty years ago Winfried Hensinger was told by other scientists that developing a powerful quantum computer was impossible. Now he has made the system behind him that he believes will prove them wrongScientists have come a step closer to making multi-tasking 'quantum' computers, far more powerful than even today's most advanced supercomputers.So-called quantum particles can be in two places at the same time and also strangely connected even though they are millions of miles apart.
"Right now we have quantum computers with very simple microchips," he said. "What we have achieved here is the ability to realise extremely powerful quantum computers capable of solving some of the most important problems for industries and society.
But Prof Hensinger's team has made a breakthrough, published in the journal Nature Communications, which may have overcome that obstacle. "To build the type of quantum computer you need in the future, you start off by connecting chips that are the size of your thumbnail until you get something the size of a dinner plate. The Sussex group has shown you can have the stability and speed for that step.
"It is really difficult to say how close we are to the realisation of quantum computing, but I'm optimistic in how it can become relevant to us in our everyday lives."

As Nicotine Pouches Get More Popular, Some Researchers Have ConcernsResearchers studying nicotine pouches, a new oral product that gives a rush similar to cigarettes but without using tobacco, are concerned about their soaring use. The tobacco-free pouches are marketed as a cleaner, more discreet way to consume nicotine. The small microfiber pouch sits in the mouth while the nicotine salt inside dissolves. They appear to be the latest trend…
