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…
Optical signatures of silicon-vacancy spins in diamond
Tina Muller, Christian Hepp, Benjamin Pingault +7
Colour centres in diamond have emerged as versatile tools for solid-state quantum technologies ranging from quantum information to metrology, where the nitrogen-vacancy centre is t…
The electronic structure of the silicon vacancy color center in diamond
Christian Hepp, Tina Müller, Victor Waselowski +8
The negatively charged silicon vacancy (SiV) color center in diamond has recently proven its suitability for bright and stable single photon emission. However, its electronic struc…
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…
Narrowband fluorescent nanodiamonds produced from chemical vapor deposition films
Elke Neu, Carsten Arend, Felix Guldner +10
We report on the production of nanodiamonds (NDs) with 70-80 nm size via bead assisted sonic disintegration (BASD) of a polycrystalline chemical vapor deposition (CVD) film. The ND…
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…
Design of microcavities in diamond-based photonic crystals by Fourier- and real-space analysis of cavity fields
Janine Riedrich-Möller, Elke Neu, Christoph Becher
We present the design of two-dimensional photonic crystal microcavities in thin diamond membranes well suited for coupling of color centers in diamond. By comparing simulated and i…
