2023 achievements

• How does a quantum computer work, and how will they change the world? Our Centre Director Prof. Winfried Hensinger explains to IFL Science how the background lies in quantum mechanics, and why the world will benefit from this new approach to computation. Prof. Hensinger also features on BBC Radio 4 All Consuming: Microchips, explaining his group's recent quantum computing breakthrough (go to 15:40).
• On 14 July, we were proud to host the annual QSNET workshop. Bringing together 30 colleagues from Sussex, Imperial, NPL, Birmingham and beyond, for a day of talks, poster presentations and networking.
• Petros Zantis of our Ion Quantum Technology group represented the Centre at COMA-RUGA 2023, International Workshop on Microwave Research and Applications. Petros presented a talk explaining how the group seek comprehensive understanding of Radio-frequency and microwave technologies which are at the heart of the quantum computer architecture they are developing.
• Our Quantum Systems and Devices group were well represented at this year's Young Atom Opticians conference, hosted by ICFO in Barcelona. Poppy Joshi, Tasha Beirrum and Leigh Thomas Page presented respectively: 'Developing a Bose-Einstein condensate microscope'; ‘Radio-frequency dressing of Bose-Einstein condensates for investigating quantum phase’; and 'A new system to automatically characterise alkali vapour-cells'.

• The Ion Quantum Technology group welcomed the BBC’s Technology Editor, Zoe Kleinman, into their labs. The visit and an interview with Prof. Winfried Hensinger feature in a programme from BBC Tech World Service, where he reveals how his childhood ambitions have shaped his research (go to 14:27).

• In March we participated in the British Ion Trap Conference BrIT-C 2023 in Teddington. Ryan Willetts of our Geonium Chip group won the runner up prize for best oral presentation with his talk The Geonium Chip Penning Trap: a novel ion trap quantum technology.
• We start the year with a paper from the Ion Quantum Technology group published by Nature Communications, led by Dr Mariam Akhtar: A High-Fidelity Quantum Matter-Link Between Ion-Trap Microchip Modules. The researchers demonstate for the first time that quantum bits can directly transfer between quantum computer microchips with record-breaking speed and accuracy. The paper has been selected to represent one of the best recently published examples of quantum research in Nature Communications Editor's highlights.
  

2022 at a glance

• Prof. Matthias Keller of our Ion Trap Cavity-QED and Molecular Physics group has an article published in Contemporary Physics titled Cavity-QED with Single Trapped Ions.
• Physicists from University of Sussex spin-out company, Universal Quantum, have secured a record-breaking investment from the German government to build a truly scalable trapped ion quantum computer within the next four years. Read more about Prof. Winfried Hensinger and Dr Sebastian Weidt's achievement, here.
• The University of Sussex Research with Impact seminar series ran a webinar focusing on quantum technology research at the University. Several of our staff and PhD students were invited to explain how research undertaken at the Centre is impacting wider technological advances. Watch the recording here. 
• In October, Prof. Winfried Hensinger offered an inspiring speech to launch the Mid Sussex STEM challenge, as reported here in Sussex World. The next generation of engineers will research and create a remote-controlled vehicle that can navigate an obstacle course at the South of England showground.
• Dr Jose Galiana Verdu of our Geonium Chip group has been awarded a share of UKRI funding worth £6m. The grant of £500,000 for 2-3 years will be funded by STFC via the call Developing Quantum Technologies for Fundamental Physics. Read about his goal to develop a quantum microwave sensor capable of measuring the absolute mass of the neutrino particle in The Quantum Insider.

• A paper published in Nature by Prof. Alessia Pasquazi and her team includes research carried out by EPic Lab at Sussex: Self-Emergence of Robust Solitons in a Micro-Cavity details how the group have overcome a major obstacle in producing a portable atomic clock. Read more about this story here.

• Members of our EPic Lab attended the Advanced Photonics Congress in Maastricht in July to present a range of their research: 'Frequency control of Laser Cavity Solitons for metrological applications' (Antonio Cutrona), 'Terahertz 3D micro-tomography via time-resolved nonlinear ghost imaging' (Dr Luana Olivieri), 'Deterministic Terahertz wave control in complex media' (Vivek Kumar), and 'Spatiotemporal superfocusing of ultrafast Terahertz waves in complex media' (Vittorio Cecconi).
• The Ion Quantum Technology group present some of the quantum control methods used for dealing with noise for trapped ions with a focus on static magnetic field gradients and microwaves approaches. Read more in their paper Quantum Control Methods for Robust Entanglement of Trapped Ions.
• Our Centre Director, Prof. Winfried Hensinger, featured on BBC 5 Live Breakfast show explaining why the UK is leading in the development of quantum computing, with applications ranging from the pharmaceutical and financial sectors, to fertiliser production (go to 2:50).
  
• Physicists in the Quantum Systems and Devices group led by Dr Mark Bason have used magnetic imaging for assessing electric vehicle batteries, detailed in this published peer reviewed paper in the Journal of Power Sources. With this new technology, the researchers can visualise the inside workings of an electric vehicle battery.
• Colleagues from the EPic Lab had the opportunity to attend the SPIE Photonics Europe Innovation Village 2022 3 - 7 April, and present their project on developing a Virtual Optical Effect (VOE) application.
• Our Sussex Quantum physicists were delighted to welcome Mims Davies, Employment Minister, to campus in April. She learned about the pioneering research taking place in our labs, as well as the potential to create a new "quantum Silicon Valley" in her Mid Sussex constituency.
• Foni Lebrun-Gallagher and colleagues in the Ion Quantum Technology group publish their paper A Scalable Helium Gas Cooling System for Trapped-Ion Applications in IoP Science.
• Imagine being able to remotely monitor environmental factors in labs which can in turn be used to control systems in inaccessible and unpredicable envrionments such as space. The Quantum Systems and Devices group have achieved this, you can read more about it here and their published paper in IoP Science.
