Scientists at Sussex University have made a breakthrough in quantum computing

Quantum computers use subatomic particles that can be in two places at once.

A team from the University of Sussex has shown they can put quantum microchips together like a jigsaw puzzle to make a more powerful quantum computer.

According to Professor Winfried Hensinger, who led the research, development will pave the way for computers to solve incredibly complex problems that even the best computers are currently unable to solve.

Prof Hesinger said: “Eventually, as quantum computers grow, we will be constrained by the size of the microchip, which limits the number of quantum bits such a chip can hold.

“Thus, we knew that a modular approach is key to making quantum computing powerful enough to solve evolving industry problems.

“By showing that we can connect two quantum computing chips – a bit like a puzzle – and most importantly that it works so well, we unlock the potential for scaling by connecting hundreds or even thousands of quantum computing microchips.”

Currently, computers can only solve problems linearly and one at a time, but quantum computers could perform multiple calculations at the same time.

Professor Sasha Roseneil, Vice Chancellor at the University of Sussex, hailed the discovery as “fantastic”.

She said: “This brings us a significant step closer to a quantum computer that will be of real benefit to society.

“These computers will have limitless applications – from improving drug development, to creating new materials, to maybe even finding solutions to the climate crisis.

“The University of Sussex is investing heavily in quantum computing to support our bold goal of hosting the world’s most powerful quantum computers and bringing about change that has the potential to positively impact so many people around the world.

“With teams covering the full spectrum of quantum computing and technology research, the University of Sussex has both a broad and broad range of expertise in the field.

“We are continuing to expand our research and teaching in this area and are planning new teaching programs and new appointments.”
