PRESS RELEASE — Researchers from the College of Sussex and Common Quantum have demonstrated for the primary time that quantum bits (qubits) can straight switch between quantum pc microchips and demonstrated this with record-breaking velocity and accuracy.  This breakthrough resolves a significant problem in constructing quantum computer systems massive and highly effective sufficient to sort out complicated issues which are of vital significance to society.

Immediately, quantum computer systems function on the 100-qubit scale. Consultants anticipate hundreds of thousands of qubits are required to resolve necessary issues which are out of attain of right now’s strongest supercomputers [1, 2]. There’s a world quantum race to develop quantum computer systems that may assist in many necessary societal challenges from drug discovery to creating fertilizer manufacturing extra power environment friendly and fixing necessary issues in almost each business, starting from aeronautics to the monetary sector.

Within the analysis paper, printed right now (Wednesday 8 February 2023) in Nature Communications, the scientists display how they’ve used a brand new and highly effective approach, which they dub ‘UQ Join’, to make use of electrical subject hyperlinks to allow qubits to maneuver from one quantum computing microchip module to a different with unprecedented velocity and precision. This enables chips to fit collectively like a jigsaw puzzle to make a extra highly effective quantum pc.

The College of Sussex and Common Quantum crew have been profitable in transporting the qubits with a 99.999993% success price and a connection price of 2424/s, each numbers are world information and orders of magnitude higher than earlier options.

Professor Winfried Hensinger, Professor of Quantum Applied sciences on the College of Sussex and Chief Scientist and Co-founder at Common Quantum stated: “As quantum computer systems develop, we’ll ultimately be constrained by the scale of the microchip, which limits the variety of quantum bits such a chip can accommodate. As such, we knew a modular method was key to make quantum computer systems highly effective sufficient to resolve step-changing business issues. In demonstrating that we will join two quantum computing chips – a bit like a jigsaw puzzle – and, crucially, that it really works so nicely, we unlock the potential to scale-up by connecting lots of and even hundreds of quantum computing microchips.”

Whereas linking the modules at world-record velocity, the scientists additionally verified that the ‘unusual’ quantum nature of the qubit stays untouched throughout transport, for instance, that the qubit may be each 0 and 1 on the identical time.

Dr Sebastian Weidt, CEO and Co-founder of Common Quantum, and Senior Lecturer in Quantum Applied sciences on the College of Sussex stated: “Our relentless focus is on offering folks with a device that may allow them to revolutionise their subject of labor. The Common Quantum and College of Sussex groups have performed one thing actually unbelievable right here that may assist make our imaginative and prescient a actuality. These thrilling outcomes present the exceptional potential of Common Quantum’s quantum computer systems to turn into highly effective sufficient to unlock the numerous lifechanging purposes of quantum computing.”

Common Quantum has simply been awarded €67 million from the German Aerospace Heart (DLR) to construct two quantum computer systems the place they’ll deploy this know-how as a part of the contract. The College of Sussex spin-out was additionally not too long ago named as one of many 2022 Institute of Physics award winners within the Enterprise Begin-up class.

Weidt added: “The DLR contract was possible one of many largest authorities quantum computing contracts ever handed out to a single firm. This can be a big validation of our know-how. Common Quantum is now working arduous to deploy this know-how in our upcoming business machines.”

Dr Mariam Akhtar led the analysis throughout her time as Analysis Fellow on the College of Sussex and Quantum Advisor at Common Quantum. She stated: “The crew has demonstrated quick and coherent ion switch utilizing quantum matter hyperlinks. This experiment validates the distinctive structure that Common Quantum has been creating – offering an thrilling route in the direction of actually large-scale quantum computing.”

Professor Sasha Roseneil, Vice-Chancellor of the College of Sussex, stated: “It’s improbable to see that the impressed work of the College of Sussex and Common Quantum physicists has resulted on this phenomenal breakthrough, taking us a big step nearer to a quantum pc that shall be of actual societal use. These computer systems are set to have boundless purposes – from enhancing the event of medicines, creating new supplies, to perhaps even unlocking options to the local weather disaster. The College of Sussex is investing considerably in quantum computing to help our daring ambition to host the world’s strongest quantum computer systems and create change that has the potential to positively influence so many individuals internationally. And with groups spanning the spectrum of quantum computing and know-how analysis, the College of Sussex has each a breadth and a depth of experience on this. We’re nonetheless rising our analysis and educating on this space, with plans for brand new educating programmes, and new appointments.”

Professor Keith Jones, Interim Provost and Professional-Vice Chancellor for Analysis and Enterprise on the College of Sussex, stated of the event: “This can be a very thrilling discovering from our College of Sussex physicists and Common Quantum. It proves the worth and dynamism of this College of Sussex spin-out firm, whose work is grounded in rigorous and world-leading educational analysis. Quantum computer systems shall be pivotal in serving to to resolve among the most urgent world points. We’re delighted that Sussex teachers are delivering analysis that provides hope in realising the optimistic potential of next-generation quantum know-how in essential areas akin to sustainability, drug growth, and cybersecurity.”
