We will host the European Research Council's (ERC) Scientific Council Meeting this June. Leading up to the visit, we are highlighting some of the projects at Durham that are happening thanks to support from the ERC.

Researchers led by Professor Simon Cornish are working at the forefront of quantum physics, using cutting-edge techniques to explore the fundamental laws of nature.

Ultracold temperatures

Through the support of ERC funding, Simon and his dedicated team have been delving into the mysteries of atoms and molecules at ultracold temperatures, reaching within a millionth of a degree of absolute zero (−273.15°C).

These extreme conditions allow them to explore the fundamental laws that govern nature at a microscopic level. This paves the way for revolutionary advancements in quantum mechanics and technology.

Innovative techniques and quantum states

Using advanced lasers and magnetic fields, the team cools and traps atoms, creating unique quantum states such as Bose-Einstein condensates.

Their ability to trap and manipulate single atoms enables them to construct matter atom by atom, pushing the boundaries of what is scientifically possible.

Global milestones in quantum entanglement

The team achieved a significant global milestone by entangling individual molecules using cutting-edge magic-wavelength optical tweezers.

This breakthrough opens up new possibilities in quantum computing, high-precision measurements, and physics research.

Unlocking new opportunities

Beyond immediate advancements in quantum computing and simulation, this research enhances our ability to explore fundamental physics with unprecedented sensitivity.

The novel magic-wavelength traps that Simon has developed allow for ultra-precise measurements of molecular energy shifts, crucial for probing physics beyond the Standard Model of physics and subtle many-body effects.

This pioneering work is contributing to national quantum technology initiatives, reinforcing the UK's position in the global quantum field and highlighting Durham's leadership in scientific progress.

World-leading research

Simon and his team continue to advance the field, aiming to increase the number of molecules that can be fully controlled in the quantum regime. This will allow them to explore novel many-body phenomena underpinning many areas of physics.

Through these various studies, Simon also mentors the next generation of researchers in ultracold molecules at Durham, ensuring a lasting legacy of scientific excellence.

This research underscores the transformative potential in shaping the future of quantum technology.
