Coherent control of the silicon-vacancy spin in diamond
Benjamin Pingault, David-Dominik Jarausch, Christian Hepp +5
Spin impurities in diamond have emerged as a promising building block in a wide range of solid-state-based quantum technologies. The negatively charged silicon-vacancy centre combi…
All-optical formation of coherent dark states of silicon-vacancy spins in diamond
Benjamin Pingault, Jonas N. Becker, Carsten H. H. Schulte +7
Spin impurities in diamond can be versatile tools for a wide range of solid-state-based quantum technologies, but finding spin impurities which offer sufficient quality in both pho…
Evaluation of nitrogen- and silicon-vacancy defect centres as single photon sources in quantum key distribution
Matthias Leifgen, Tim Schröder, Friedemann Gädeke +8
We demonstrate a quantum key distribution (QKD) testbed for room temperature single photon sources based on defect centres in diamond. A BB84 protocol over a short free-space trans…
Low temperature investigations of single silicon vacancy colour centres in diamond
Elke Neu, Christian Hepp, Michael Hauschild +6
We study single silicon vacancy (SiV) centres in chemical vapour deposition (CVD) nanodiamonds on iridium as well as an ensemble of SiV centres in a high quality, low stress CVD di…
Visible-to-telecom quantum frequency conversion of light from a single quantum emitter
Sebastian Zaske, Andreas Lenhard, Christian A. Kessler +8
Quantum frequency conversion (QFC), a nonlinear optical process in which the frequency of a quantum light field is altered while conserving its non-classical correlations, was firs…
One- and two-dimensional photonic crystal micro-cavities in single crystal diamond
Janine Riedrich-Möller, Laura Kipfstuhl, Christian Hepp +10
The development of solid-state photonic quantum technologies is of great interest for fundamental studies of light-matter interactions and quantum information science. Diamond has…
Single-photon emission from Ni-related color centers in CVD diamond
David Steinmetz, Elke Neu, Christian Hepp +5
Color centers in diamond are very promising candidates among the possible realizations for practical single-photon sources because of their long-time stable emission at room temper…
