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…

Tapered fiber coupling of single photons emitted by a deterministically positioned single nitrogen vacancy center

Lars Liebermeister, Fabian Petersen, Asmus v. Münchow +11

A diamond nano-crystal hosting a single nitrogen vacancy (NV) center is optically selected with a confocal scanning microscope and positioned deterministically onto the subwaveleng…

Mode structure and polaritonic contributions to the Casimir effect in a magneto-dielectric cavity

Harald R. Haakh, Francesco Intravaia

We present a full analysis of the mode spectrum in a cavity formed by two parallel plates, one of which is a magneto-dielectric, e.g. a metamaterial, while the other one is metalli…

Probing the local density of states in three dimensions with a scanning single quantum emitter

Andreas W. Schell, Philip Engel, Oliver Benson

Their intrinsic properties render single quantum systems as ideal tools for quantum enhanced sensing and microscopy. As an additional benefit, their size is typically on an atomic…

Observation of the Quantum Zeno Effect on a Single Solid State Spin

Janik Wolters, Max Strauß, Rolf Simon Schoenfeld +1

The quantum Zeno effect, i.e. the inhibition of coherent quantum dynamics by projective measurements is one of the most intriguing predictions of quantum mechanics. Here we experim…
