Researchers awarded £ 6.1 million to study luminescent semiconductors for quantum science and technology

Researchers at the University of Sheffield have been awarded £ 6.1 million to study luminescent semiconductor nanostructures.

The program, led by Professor Maurice Scornick, aims to leverage advanced technology to discover a radically new system of nanophotonic phenomena that may underpin next-generation quantum technology.

The team, which includes eight collaborators from the University of Sheffield, University College London, and the University of Manchester, received a £ 6.1 million grant from the Institute of Engineering and Physical Sciences for this research.

Our research focuses on luminescent semiconductor materials. Such materials emit light very efficiently and dominate many aspects of everyday life, enabling the internet, large area displays, rooms and streetlights. Their presence relies on high quality semiconductor structures that may be prepared by advanced crystal growth and advanced nanofabrication.

“By using this, we aim to achieve fundamental advances in quantum photonics, from the region of several photons to the density of states containing tens of millions of electrons, holes, and photons. The results have great potential to support next-generation quantum technology. “

The team studies on-chip geometries and enables the scale-ups that applications may require. Due to the strong interaction between semiconductor materials and photons, researchers realize interactions between photons that normally do not interact. This is an important requirement for logic gates operating at the single photon level.

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

The diversity of these semiconductor nanostructures also allows access to dense regions where electrons and holes condense into a densely populated state. This allows the team to answer long-standing basic questions about the types of phase transitions that can occur in equilibrium and out-of-balance systems. In addition to its basic interest, the condensed state system has the potential as a new form of miniature coherent light source.
