necessary renewal of satellites.’ A radiation model of the Celesta
satellite was also tested in Charm, a Cern mixed-field facility capable of reproducing the radiation environment of low Earth orbit. The mission will be an important validation of this capability at the facility. ‘Capable of testing satellites all at once, rather than component by component, Charm is a unique installation
worldwide, remarkably different from other irradiation test facilities. It offers a simple, low-cost alternative and the possibility to assess system-level effects,’ says Salvatore Danzeca, Charm facility coordinator. The success of this satellite is
the result of a fruitful partnership between Cern and the University of Montpellier, which involved many students from both institutions
and radiation effect specialists from Cern. Celesta is based on the CSUM radiation-tolerant platform. It will be operated from the CSUM control centre. The European Space Agency provided the launch slot in the framework of its small satellite programme. Enrico Chesta, Cern’s
Aerospace and Environmental Applications Coordinator in the Knowledge Transfer Group, adds:
‘On a mission to make space more accessible, Celesta is an exciting example of how Cern expertise can have a positive impact on the aerospace industry. ‘With this mission, Cern
displays its low-cost solutions for measuring radiation and testing satellites against it – thus providing universities, companies and start-ups with the means to realise their space ambitions.’
MODELLING AND SIMULATION Collaboration explores quantum computing for semiconductor research
Quantinuum has announced a global collaboration with materials technology leader JSR Corporation of Japan to explore the application of quantum computing methods in semiconductor research. The collaboration brings together JSR’s
world-leading materials scientists with quantum computing experts at Quantinuum in Japan, Europe and the USA. The joint team will use the state-of-the-art InQuanto software platform to explore methods using quantum computers to model semiconducting materials, such as metal complexes and transition metal oxides. These materials are essential to
microelectronics. It is hoped new modelling methods using quantum computers may achieve accurate predictions of their physical properties that, in the future, could accelerate the identification of new candidate molecules and materials and open the way to future microelectronic device paradigms. Rei Sakuma, Principal Researcher of the
Materials Informatics Initiative of JSR, says: ‘We are delighted to have formed this new
32 Scientific Computing World Summer 2022
collaboration with Quantinuum, which builds on our previous work together. The Quantinuum team continues to lead the quantum computing hardware and software field, complementing our scientists’ deep expertise in materials innovation. Our aspiration is to develop materials that can enrich society and the environment. Quantinuum’s software platform InQuanto is already helping our team to better understand how quantum computing may help us accelerate our path towards that ambitious goal.’ The collaboration will focus on developing quantum algorithms and methods based on dynamical mean-field theory (DMFT). This approach could provide a more accurate understanding of the electronic properties of complex organic and inorganic materials in the real world, such as optical absorption and conductivity, which could pave the way for future progress in the silicon-based information age. Quantinuum and JSR will use InQuanto to
explore new methods to model these complex molecular systems and defect subsystems. The new methods discovered will be incorporated
into InQuanto, and will become available for the use of other scientists and researchers using the software platform. Ilyas Khan, CEO of Quantinuum, says: ‘The
work we do with JSR is at the absolute cutting edge of materials science using quantum computers and we are thrilled to continue our relationship. This work will further develop InQuanto’s functionality, ensuring that new developments will become available to other users. This is the value of such a collaboration: JSR’s scientists know materials science, we know quantum computing and the scientific community benefits.’ InQuanto was recently launched as a
stand-alone platform and brings together the latest algorithms, methods and noise mitigation techniques used by molecular and materials scientists and researchers on quantum computers and emulators. It will give JSR’s scientists and researchers a greater understanding of the capabilities of quantum computers in their path towards quantum advantage in computational chemistry.
