Scientific breakthrough may take us nearer to impactful quantum computer systems

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 straight switch between quantum pc microchips.

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

To deal with these points, consultants estimate that tens of millions of qubits are required — a quantity presently out of attain, with current quantum computer systems working on the 100-qubit scale.

“As quantum computer systems develop, we are going to ultimately be constrained by the scale 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 group developed a novel method, named “UQ Join.” This technique enabled the researchers to make use of electrical discipline hyperlinks that permit qubits to maneuver from one quantum computing microchip module to a different with record-breaking pace and accuracy. Particularly, the researchers have been profitable in transporting 2,424 ion qubits per second with a 99.999993% success price.

“We knew a modular method was key to make quantum computer systems highly effective sufficient to resolve step-changing trade issues. In demonstrating that we are able to 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 a whole lot, and even hundreds of quantum computing microchips,” Hensinger added.

Common Quantum, which was just lately 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 know-how.

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