University of Sheffield to lead multi-million pound project which could open up a new frontier in physics

Quantum Sensing for the Hidden Sector (QSHS), is the best supported and largest UK effort in hidden sector physics to date, and involves scientists from a range of disciplines within physics.

A collaboration of scientists from across the UK are working on a new project to detect hidden particles, the discovery of which could open up a new frontier in fundamental physics.

University of Sheffield researchers awarded £6.1m to study light emitting semiconductors for quantum science and technology

Researchers at the University of Sheffield have been awarded £6.1m to study light emitting semiconductor nanostructures.

Led by Professor Maurice Skolnick, the programme aims to capitalise on advanced technology to discover fundamentally new regimes of nanophotonic phenomena, with potential to underpin the next generation of quantum technologies.

The team, which involves eight co-investigators at the University of Sheffield, University College London and the University of Manchester, has been awarded a £6.1m grant for this research by the Engineering and Physical Sciences Research Council.

Our research focuses on light emitting semiconductor materials. Such materials emit light very efficiently and dominate many aspects of everyday life, enabling things like the internet, large area displays, room and street lighting. Their existence relies on the high quality semiconductor structures which may be prepared by advanced crystal growth and sophisticated nanofabrication.

By capitalising on this, we aim to achieve fundamental advances in quantum photonics ranging from the regimes of few photons to highly dense states containing many tens of millions of electrons, holes and photons. The findings have considerable potential to underpin next generations of quantum technologies.”

The team will research on-chip geometries, enabling scale-up as likely required for applications. Due to the strong interaction of semiconductor materials with photons the researchers will achieve interactions between photons which normally do not interact, a key requirement for logic gates operating at the level of single photons.

This will give the researchers insight into the regime of highly non-linear phenomena at the few photon level. By coupling photons in cavities together, they are aiming for highly correlated states of photons, likely to be important components of photonic quantum processors and quantum communication systems.

The versatility of these semiconductor nanostructures will also allow access to regimes of high density where electrons and holes condense into highly populated states. This will allow the team to answer long-standing fundamental questions about the types of phase transitions that can occur in systems both in and out of equilibrium with their surroundings. The condensed state systems, besides their fundamental interest, also have potential as new forms of miniature coherent light sources.

Opening of the Sheffield Quantum Centre

The Sheffield Quantum Centre is now officially open! We celebrated the formal opening and launch of the Quantum Technology MBE Capital Equipment on Wednesday, 22 January 2020 in The Diamond, University of Sheffield, 32 Leavygreave Rd, Sheffield S3 7RD.

The opening of the Centre was carried out by Lord Jim O’Neill chair of Chatham House, promoter of the Northern Powerhouse and Sheffield alumnus (https://www.chathamhouse.org/expert/jim-oneill), and the Vice-Chancellor of Sheffield University, Professor Koen Lamberts.  The day was composed of the formal opening, talks on the UK National QT Programme, the Sheffield Centre and the new equipment. It was also held in conjunction with the MSCA ITN 4PHOTON Winter school, where relevant scientific talks were presented by leaders in the quantum dot and nanophotonics fields.

A selection of photos from the day have been uploaded below.
