High-cooperativity coupling and spin-resolved extinction of tin-vacancy centers in a diamond-like microcavity
Kerim Köster, András Laukó, Federico Rapisarda +16
The tin-vacancy (SnV) center in diamond is a promising spin-photon interface for quantum networks, combining favorable optical properties with spin coherence above 1K. Unfolding th…
Revealing and reducing growth-induced interfacial disorder in preferentially aligned nitrogen-vacancy centers in diamond
Cheng-I Ho, Marina Davydova, Patrik Straňák +6
Nitrogen-vacancy (NV) centers in chemical-vapor-deposition (CVD) diamond can form preferentially oriented ensembles with high sensing performance and low densities of lattice defec…
Delta-Doped Diamond via in-situ Plasma-Distance Control
Philip Schätzle, Felix Hoffmann, Sven Mägdefessel +3
We present an approach for the CVD growth of diamond, where the sample is placed in a defined distance from the reactor baseplate, to which the plasma couples. We observe two previ…
Readout of a solid state spin ensemble at the projection noise limit
Rouven Maier, Cheng-I Ho, Andrej Denisenko +4
Spin ensembles are central to quantum science, from frequency standards and fundamental physics searches to magnetic resonance spectroscopy and quantum sensing. Their performance i…
The properties of the nitrogen-vacancy center in milled chemical vapor deposition nanodiamonds
Alessandro Mameli, Giannis Thalassinos, Marco Capelli +14
Fluorescent nanodiamonds (FNDs) containing negatively charged nitrogen-vacancy (NV-) centers are vital for many emerging quantum sensing applications from magnetometry to intracell…
Spin coherence in strongly coupled spin baths in quasi-two-dimensional layers
Philip Schätzle, Reyhaneh Ghassemizadeh, Daniel F. Urban +5
We investigate the spin-coherence decay of NV-spins interacting with the strongly-coupled bath of nitrogen defects in diamond layers. For thin diamond layers, we demonstrate th…
