National Epitaxy Facility receives further funding

Professor Jon Heffernan, Director of the National Epitaxy Facility, is delighted to announce that following a community statement-of-need in 2019 and a competitive bid to EPSRC, the National Epitaxy Facility has been funded for a further five years from 1 July 2022.

The Facility, led by the University of Sheffield and with the Universities of Cambridge and UCL as partners, is fulfilling a critical role in semiconductor innovation in the UK, building on a 40-year history of providing epitaxial wafers to both the academic and industrial research community.

Visit the National Epitaxy Facility website for more information on capabilities and new features of the Facility including heterogeneous integration, an increased range of materials on offer, and opportunities for PhD training.

LDSD Fellowship Success

We are delighted to report recipients include Alistair Brash who is a current experimental RA and Yingkai Ouyang who is a former theory RA and is currently at the National University of Singapore.

Their fellowship programmes are titled “Controlling environmental interactions for novel solid-state quantum technologies” (Brash) and “Integrating quantum sensors with bespoke quantum error correction” (Ouyang) and complement our existing experimental and theoretical research in LDSD. More details about the scheme on the UKRI website

Congratulations to Alistair and Yinkgai on their success, which funds their research for five years and includes RA (EPSRC) and PGR (Sheffield) support.

Today sees the publication of two papers from our group.

The first is a Nature Photonics paper titled “Optical analogue of Dresselhaus spin–orbit interaction in photonic graphene”, which is available for viewing online.

The second is an Optica paper titled “Chiral topological photonics with an embedded quantum emitter”, and is available for reading online.

Congratulations to all involved in this work.

LDSD seminar series

19 October 2020

October 2020 marks the return of the LDSD seminar series, where physicists working in the field of nanophotonics present their research virtually.

Last Thursday 15th October saw Dr Hamidreza Siampour from the University of Sheffield present his work on “Hybrid quantum photonics with nanodiamonds and plasmons”, and next Monday 26th October will see Dr Edward Laird from the University of Lancaster present his work titled “A coherent mechanical oscillator driven by single-electron tunnelling”.

Abstracts of upcoming seminars will be released when available on our Events page.

On 23 July 2020, after a lengthy lockdown period, we are pleased to announce the reopening of our research labs.

LDSD group holds seventh Programme Grant Away Day

27 January 2020

On 27 January 2020, the LDSD group held its seventh Away Day of the Programme Grant at The Edge in the Endcliffe Village, which saw all four work packages present their current research via informative presentations and a poster session. The day was a success, boasting around 40 attendees, including the EPSRC and our Advisory Committee.

Quantum Centre opening

29 July 2019

This year has been a very busy year for our outreach activities, presenting our Quantum Light exhibit at Discovery Night, the Exploring STEM for Girls event and returning to the Cheltenham Science Festival. Between these three events we have encouraged thousands of people to explore the exciting world of quantum light and hopefully inspired a number of them to become the next generation of quantum researchers. We were also thrilled to discover that so many attendees shared our excitement about quantum physics, we look forward to meeting many more of you at our future events.

LDSD group holds sixth Programme Grant Away Day

24 July 2019

On 23 July 2019 the group held the sixth Away Day of its Programme Grant, during which leaders of the four work packages reported on progress to date. The photo shows all attendees gathering together before lunch.

LDSD outreach animation achieves international scale

1 July 2019

LDSD outreach animation achieves international scale.

An image from an animation prepared in our group ( was used as part of a presentation to explain quantum optics to members of the public in Lecce, Italy. The presentation in Italian was made as part of the TERAMETANANO-4 conference. The inclusion of our animation, originally prepared to communicate these fascinating concepts in physics to the public, shows that it continues to achieve its aim and provides a useful tool for the international science community.

Celebration of journal publications

26 June 2019

A celebration was held on 4 April 2019 in recognition of the recent publication of one paper in Nature: Nature 567, 81, (2019), two in Physical Review Letters: Phys. Rev. Lett. 122, 096801, (2019) and Phys. Rev. Lett. 122, 173603, (2019) and one in Optics Express: Optics Express 27, 10692, (2019).

Congratulations to all!
