Advances in Quantum Metrology with Dielectrically Structured Single Photon Sources Based on Molecules

open access: yesAdvanced Quantum Technologies, Volume 7, Issue 10, October 2024.
Exploiting the integration in polymeric micro‐lenses, a new generation of molecule‐based single‐photon sources for quantum radiometry is presented. The emitters exhibit enhanced efficiency and improved stability, as their optical properties result largely unaffected by a successive cooling‐heating cycle.

Hard X‐ray operation of X‐ray gas monitors at the European XFEL

open access: yesJournal of Synchrotron Radiation, Volume 31, Issue 4, Page 681-689, July 2024.
The operation of X‐ray gas monitors at the European XFEL at hard photon energies up to 30 keV is described, and the possibilities and limitations for future operation up to 50 keV are discussed.X‐ray gas monitors (XGMs) are operated at the European XFEL for non‐invasive single‐shot pulse energy measurements and average beam‐position monitoring.

Directional spontaneous emission in photonic crystal slabs

open access: yesNanophotonics, Volume 13, Issue 11, Page 1963-1973, May 2024.
Abstract Spontaneous emission is one of the most fundamental out‐of‐equilibrium processes in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. In this process, a photon is emitted that can interact with other nearby emitters and establish quantum correlations between them, e.g., via super and subradiance effects.
