In a world first, scientists from the College of Sussex and Universal Quantum, a spin-off of the college, have demonstrated that quantum bits (qubits) can instantly switch between quantum pc microchips.

This breakthrough is predicted to beat a significant impediment in constructing quantum computer systems which are giant and highly effective sufficient to deal with the essential societal challenges they’re envisioned to: from drugs growth, to the creation of latest supplies and local weather change options.

To handle these points, specialists estimate that hundreds of thousands of qubits are required — a quantity presently out of attain, with present quantum computer systems working on the 100-qubit scale.

“As quantum computer systems develop, we’ll finally be constrained by the dimensions of the microchip, which limits the variety of quantum bits such a chip can accommodate,” Winfried Hensinger, Professor of Quantum Applied sciences on the College of Sussex and Chief Scientist and co-founder at Common Quantum explained.

As an answer, the analysis staff developed a novel method, named “UQ Join.” This technique enabled the researchers to make use of electrical area hyperlinks that enable qubits to maneuver from one quantum computing microchip module to a different with record-breaking velocity and accuracy. Particularly, the researchers have been profitable in transporting 2,424 ion qubits per second with a 99.999993% success charge.

“We knew a modular method was key to make quantum computer systems highly effective sufficient to unravel step-changing trade issues. In demonstrating that we will join two quantum computing chips — a bit like a jigsaw puzzle — and, crucially, that it really works so effectively, we unlock the potential to scale up by connecting lots of, and even 1000’s of quantum computing microchips,” Hensinger added.

Common Quantum, which was not too long ago named one of many 2022 Institute of Physics winners within the Enterprise Startup class, has now been awarded €67 million from the German Aerospace Middle (DLR) to construct two quantum computer systems that can deploy the brand new expertise.

“The DLR contract was probably one of many largest authorities quantum computing contracts ever handed out to a single firm. It is a large validation of our expertise. Common Quantum is now working onerous to deploy this expertise in our upcoming business machines,” Dr Sebastian Weidt, CEO and co-founder of Common Quantum, and Senior Lecturer in Quantum Applied sciences on the College of Sussex, said.
