Quantum projects launched to solve universe’s mysteries

Researchers will use cutting-edge quantum technologies to transform our understanding of the universe and answer key questions such as the nature of dark matter and black holes. UK Research and Innovation (UKRI) is supporting seven projects with a £31 million investment, including two involving the University of Warwick, to demonstrate how quantum technologies could solve some of the greatest mysteries in fundamental physics.

Just as quantum computing promises to revolutionise traditional computing, technologies such as quantum sensors have the potential to radically change our approach to understanding our universe. In ‘Quantum-enhanced interferometry for New Physics’ involving Dr Animesh Datta of the University of Warwick, researchers led by Cardiff University aim to develop novel interferometers (devices capable of measuring the tiniest of length fluctuations through interference of light) to search for dark matter and for quantum aspects of space time. The project has received funding of £4 million.

Dr Datta, of the University’s Department of Physics, said: “This project will seek experimental signatures of hypothesised particles of Nature such as dark matter and hypothesised theories such as quantum aspects of gravity. There is as yet no such evidence. Warwick’s work will focus on theoretically designing such novel experiments using our expertise in quantum information science.” Dr Yorck Ramachers and colleagues from the University of Warwick Department of Physics will be involved in ‘Determination of Absolute Neutrino Mass using Quantum Technologies’ led by University College London, which has received funding of £3.8 million. The project aims to harness recent breakthroughs in quantum technologies to solve one of the most important outstanding challenges in particle physics – determining the absolute mass of neutrinos.

Dr Ramachers said: “The measurement of the absolute neutrino mass would lead to significant progress in fundamental particle physics and cosmology related to the origin of matter and evolution of the Universe. This project will drive quantum technologies from applied physics research to advance independent fundamental physics in an interdisciplinary collaboration. Warwick’s role in this project is to bridge fundamental neutrino physics and plasma physics (as a Warwick internal collaboration, a first for Warwick) to quantum technologies developed by collaborators. As such, this project opens a new strategic direction for the particle physics group at Warwick with the potential for new collaborative projects between applied quantum technology research and fundamental physics interests.”

The projects are supported through the Quantum Technologies for Fundamental Physics programme, delivered by the Science and Technology Facilities Council (STFC) and the Engineering and Physical Sciences Research Council (EPSRC) as part of UKRI’s Strategic Priorities Fund. The programme is part of the National Quantum Technologies Programme.

Professor Mark Thomson, Executive Chair of the Science and Technology Facilities Council, said: “STFC is proud to support these projects that utilise cutting-edge quantum technologies for novel and exciting research into fundamental physics.

“Major scientific discoveries often arise from the application of new technologies and techniques. With the application of emerging quantum technologies, I believe we have an opportunity to change the way we search for answers to some of the biggest mysteries of the universe. These include exploring what dark matter is made of, finding the absolute mass of neutrinos and establishing how quantum mechanics fits with Einstein’s theory of relativity.

“I believe strongly that this exciting new research programme will enable the UK to take the lead in a new way of exploring profound questions in fundamental physics.”

Professor Dame Lynn Gladden, Executive Chair of the Engineering and Physical Sciences Research Council and UKRI sponsor for Quantum Technologies, said: “The National Quantum Technologies Programme has successfully accelerated the first wave of quantum technologies to a maturity where they can be used to make advances in both fundamental science and industrial applications.

“The investments UKRI is making through the Quantum Technologies for Fundamental Physics programme allows us to bring together the expertise of EPSRC and STFC to apply the latest advances in quantum science and technology to explore, and answer, long-standing research questions in fundamental physics. This is a hugely exciting programme and we look forward to delivering these projects and funding further work in this area as well as exploring opportunities for exploiting quantum technologies with other UKRI partners.”

Science Minister Amanda Solloway said: “As we build back better from the pandemic, it’s critical that we throw our weight behind new transformative technologies, such as quantum, that could help to unearth new scientific discoveries and cement the UK’s status as a science superpower.

“Today’s funding will enable some of the UK’s most ambitious quantum researchers to develop state of art technologies that could help us solve important unanswered questions about our universe, from proving Einstein’s theory of relativity to understanding the mysterious behaviour of black holes.”

Eating disorders worsened during Covid-19 pandemic, Bournemouth University research finds

Sun Jan 17 , 2021
The Covid-19 pandemic has led to a worsening of eating disorder symptoms, Bournemouth University (BU) research has found. The study, published in the Journal of Eating Disorders, examined which aspects of the pandemic have been especially difficult for people with eating disorders and any resulting change in their symptoms. Researchers […]

European Higher Education Organization is a public organization carrying out academic, educational and information activities on higher education in Europe.

The EHEO general plan stresses that:

  • Higher education systems require adequate funding and, as an investment in economic growth, public spending in higher education should be protected.
  • The challenges faced by higher education require more flexible governance and funding systems, which balance greater autonomy for education institutions with accountability to stakeholders.

Thus, EHEO plans:

  • improve academic and scientific interaction of universities;
  • protect the interests of universities;
  • interact more closely with public authorities of European countries;
  • popularize European higher education in the world;
  • develop academic mobility;
  • seek funding for European universities.
