Research into single-photon sources receives extensive coverage in scientific journals

EMPIR project Single-photon sources as new quantum standards (17FUN06, SIQUST) is carrying out the fundamental work needed to develop a new quantum standard, assessing and establishing new materials and designs for single-photon sources. Light sources that can emit single photons are a building block of optical quantum technologies, which have far-reaching applications from low-flux radiometry and ultra-secure communication to biomedical imaging.

The work of the project has resulted in a number of scientific papers, some of which have featured in high-profile publications. These are:

• Single-Photon Emitters in Lead-Implanted Single-Crystal Diamond was given extensive coverage. It was published in the journal ACS Photonics, and also featured on the front cover illustration. In addition, it was also advertised to the general public through a series of press releases including Frida forum della ricercar di ateneo. Furthermore, this research was extensively reviewed in a paper entitled Quantum nanophotonics with group IV defects in diamond published in Nature Communications
• Feasibility study towards comparison of the g⁽²⁾(0) measurement in the visible range was featured in the Research Highlights of Nature Physics 
• Quantum Micro–Nano Devices Fabricated in Diamond by Femtosecond Laser and Ion Irradiation was selected for the back cover illustration of Wiley Advanced Quantum Technologies journal
• A session dedicated to the topics explored within the SIQUST project was held at the conference From foundations of quantum mechanics to quantum information and quantum metrology & sensing. The session opened with a keynote talk delivered by project coordinator Stefan Kück from PTB and was followed by seven talks delivered by consortium members and internationally recognised experts in the field.

This EMPIR project is co-funded by the European Union's Horizon 2020 research and innovation programme and the EMPIR Participating States.
